There is no ambiguity in the definition of FITS for BITPIX=16: FITS readers should always construe 16-bit pixels as 2-s complement signed integers. FITS readers should also obey the BSCALE and BZERO keywords when they are present (and should default to BSCALE=1 and BZERO=0 when they are absent).

The camera software should subtract 32768 from the pixels (or, equivalently, add 8000_hex) and set BZERO=32768 and BSCALE=1 in the header.

Award-winning Spyglass Transform set the visual data analysis standard for excellence by combining powerful capabilities with an easy-to-use interface. This point-and click approach allows user to quickly, and interactively analyze large datasets. Already established in the Macintosh and UNIX markets, Spyglass Transform is a visual data analysis tool that allows scientists and engineers to quickly analyze large matrix and image datasets. With Spyglass Transform, surface plots, color raster images, line graphs, contour plots and vector plots can be created from matrix data arrays with simple point-and-click operations that require no programming. Spyglass Transform's versatile data import capability makes it extremely easy for users to import datasets from from ASCII spreadsheet files or binary data files. Spyglass Transform also automatically reads MATLAB(R), GIF, PBM, and XWD files, as well as FITS, HDF, and TIFF files. With Spyglass Transform, users can quickly and easily add floating point annotations, titles, axis labels, numerical scales, tick marks, and color bars. These features let users create high-quality plots and output them directly to color PostScript printers. Spyglass Transform also includes a powerful macro scripting language that gives the user explicit control over all Transform functions. With the macro language it is easy to automate repetitive tasks such as importing data, manipulating arrays, creating plots, adding labels, and exporting images and data. Users can even automatically generate macros of Transform generated plots, and apply those macros to other datasets. Macro commands can also be sent from other programs, making it possible to turn Spyglass Transform into a visual data analysis post processor. The macro language, also includes looping structures for repetitive operations on multiple datasets. Spyglass Transform can also create animated movies of data or image files. Animations can then be played back using the Windows Media Player. In addition, Spyglass Transform can communicate with Mathematica(R) using MathLink(R). This important feature makes it easy for users to make high-quality images and plots of their Mathematica-derived mathematical functions using Spyglass Transform. "Having the two leading technical software packages talk to each other is very synergistic," said Dr. Brand Fortner, a Spyglass cofounder. "Now, I can send my Mathematica-generated functions to Transform and interactively create high-quality images of my function. I can also use Mathematica's powerful language to automate complex Transform tasks." Spyglass Transform for Windows and Windows NT, list price $595, will begin shipping January 17, 1994. Spyglass Transform is also available for color-capable Macintosh computers, and the following UNIX platforms: Sun SPARC; Hewlett-Packard HP 9000; Silicon Graphics; Digital ULTRIX, and IBM RS/6000 workstations. Spyglass is also announcing their plans to release Spyglass Slicer, a volumetric visualization tool for Windows and Windows NT. Features of Spyglass Slicer include isosurfacing; oblique slicing; advanced voxel-based ray tracing; fast front-to-back rasterizing; key animation scripting and generation; and much more. Spyglass Slicer will be available for Windows and Windows NT and is scheduled for release in Spring, 1994 with a list price of $695. Founded in 1990, Spyglass Inc. is the leading developer of visual data analysis tools for Windows, UNIX and Macintosh platforms. Spyglass offers a suite of data analysis tools including Spyglass Plot, a column data analysis tool, and Spyglass Dicer(R), a volumetric visualization tool for Macintosh. Spyglass products are used worldwide by thousands of scientists and engineers who want to quickly and easily analyze and present their data. ### Spyglass is a registered trademark of Spyglass Inc.

The above does not specify whether an ASCII table or a binary table is intended. The proposed structure appears to fit most naturally in an extension of type BINTABLE, where the array could appear as a single field. There has been some talk, particularly within the single dish community, of conventions for use of the terms CRVALn, CRPIXn and CDELTn to describe an array contained in one field of a binary table. Perhaps one of the people involved could step forward and say where this discussion stands. > By the way, is there any documentation for >the extension 'IMAGE' or is it just too obvious to bother.

The ftp site at fits.cv.nrao.edu should have a copy of it, as well as a copy of the subsequent discussion. In the meantime, our local FITS working group has further expanded on this idea, and is drafting a document describing a proposed set of coordinate system keywords for various types of FITS image representations (not just in a primary HDU). This is directly based on and extends the 24 Aug 1993 draft of the document entitled 'Representation of Celestial Coordinates in FITS' by Greisen and Calabretta.

In 1989 there was a meeting in Green Bank, WV to discuss a FITS convention for single dish data sets. There was a draft document from that meeting which was never published. However programs were written in Green Bank as part of the UniPops single dish data analysis system to support this format. Basically each table row can contain a data matrix similar to the basic FITS primary data array. Since NAXIS is already used by the bintable convention the keywords MAXIS, MAXIS1, ...MAXISn were used to define the table matrix field. Note that MAXIS1 could be a table column so that the shape and size of the matrix could vary from row to row. The keyword NMATRIX in the binary table header indicates that this MAXIS convention is being followed. The standard FITS WCS information could also be contained in table columns. This format while not widely supported has been used by several single dish analysis programs for exchanging spectral line data. In the following example the binary table contains in each row a data spectrum plus columns for the stardard FITS CRVAL1, CRPIX1, and CDELT1 defining the spectrum. XTENSION= 'BINTABLE' / FITS binary table. BITPIX = 8 / Binary data. NAXIS = 2 / Table is a Matrix. NAXIS1 = 4100 / Width of table in bytes. NAXIS2 = 8 / Number of entries (rows) in Table. PCOUNT = 0 / No Random Parameters. GCOUNT = 1 / Only one group. TFIELDS = 5 / Number of fields in each row. NMATRIX = 1 / Number of matrixes MAXIS = 1 / No. axes in data matrix. CTYPE1 = 'FREQ ' / Frequency Axis. TFORM1 = '1I ' / TTYPE1 = 'MAXIS1 ' / Number of data points in spectrum. TFORM2 = '1D ' / TTYPE2 = 'CRVAL1 ' / Frequency at reference Pixel. TUNIT2 = 'HZ ' / TFORM3 = '1E ' / TTYPE3 = 'CRPIX1 ' / Frequency Reference Pixel. TFORM4 = '1E ' / TTYPE4 = 'CDELT1 ' / Frequency increment. TUNIT4 = 'HZ ' / TFORM5 = '1024E ' / TTYPE5 = 'SPECTRUM ' / Observed Spectrum.

This will mostly likely be published later this year. There will be some small changes from the draft document. Keep in mind that the following is from an initial draft of this paper and that the final published version may be different. EXTNAME = 'SINGLE DISH ' This indicates that the table follows the published (as soon as they are published) standards (will also optionally include EXTVER and EXTLEVEL keywords). TMATXnnn = T This keyword indicates that the axes corresponding to the array found in column nnn are those indicated by the axis descriptors in the keywords and other columns of the table (the CRVALn, CRPIX, etc, either via keywords or TTYPE, TFORM, etc). This was NOT in the draft document nor is it currently implemented in the NRAO single dish FITS writer. It is required so you can be certain which arrays are associated with the array axis descriptors (there may be other arrays in a binary table, TMAXnnn is assumed to be F when not specified). The primary data column will be named 'DATA', i.e.: TTYPE5 = 'DATA ' / Observed data Finally, although the MAXIS and MAXISnnn convention was adopted at the Green Bank meeting, a more compact notation is now favored in binary tables. The MAXIS and MAXISnnn specifications (keywords) could be replaced with the single line: TDIMnnn = (MAXIS1, MAXIS2, ...) where actual numbers corresponding to MAXIS1, etc, would be used. e.g. TDIM13 = (256,1,1,1,1) would corresponds to MAXIS = 5, MAXIS1 = 256, MAXIS2 = 1, etc. Both conventions will be outlined in the eventual paper although I think the emphasis will be on the TDIMnnn convention.

This only works if the arrays are of fixed size for each row and the MAXISnnn values are set by keywords and not by column values. This works fine for most spectral line data. However the MAXIS convention is much more powerful if the MAXIS values are column entries. This allows the shape of the data array to vary on a per row basis. Combined with the variable length array convention this more general approach could efficiently mix both line and continuum data in one FITS binary table. In general the TDIMnnn = (MAXIS1, MAXIS2, ...) is not consistant with the MAXIS approach and the two should probably not be used in the same file. The Green Bank convention only supports one array per row and one WCS per row ( if more than one array they must be of the same shape and have the same WCS). If a table needs to hold more than one array type with more than one WCS per row then some other set of conventions needs to be defined.

This is a frequently-asked-question. The FITS community needs to have a comprehensive answer to this question, but I am not aware of one at the moment.
