In conjunction with the Hubble Space Telescope (HST) project the National Space Science Data Center (NSSDC) is distributing via network and magnetic tape some of the HST Early Release observations. This directory contains some of the first results obtained with the Hubble Space Telescope cameras. These data were obtained by the Investigation Definition Teams during August 1990 as part of the Science Assessment and Early Release observations. Further details of these programs can be found in the August issue of the STScI Newsletter. The Hubble Space Telescope project is releasing these data now to facilitate the reassessment of HST observing programs. Accordingly, this data has been distributed to all general observers and guaranteed time observers who have HST time in forthcoming observing cycles. A second data set containing spectrograph observations will be compiled and distributed once these data are in hand (probably by early November). The HST project is also compiling a collection of OTA point spread function images for their own analysis of the spherical aberration and plan to have these data generally available in the months ahead. You should bear in mind when inspecting these images that they are early data, and not all the software bugs have been fixed nor all the calibration wrinkles ironed out. In particular, many of the Files used to calibrate the data are derived from ground observations which are now inappropriate. In other words: treat the data with care. Scientific investigations utilizing these data are already underway by the Investigation Definition Teams. The IDTs are going to submit the scientific results for rapid publication. Specific contacts for these data are given on the next page. Please talk with the PIs or the contact scientists if you have questions about the data.

The FOC IDT are at STScI. Two observations of SN1987A were taken. The one included on this tape is from a GO program with Bob Kirshner (CfA, Harvard) as PI. This directory containes 7 WF/PC processed science images (WF/PC unprocessed images and flat fields are included on the full tape distribution).

Both uncalibrated and calibrated images are provided in this directory for the FOC. However only the calibrated WF/PC data are stored online. The ".d0h" file extension indicates the uncalibrated image and the ".c0h" and ".c1h" (for FOC only) extensions indicates images after routine calibration. Also included are the standard headers, ".shh", for FOC. You may request the full tape distribution or individual files for network distribution by sending your request to the NSSDC request office at the address given at the end of this file. The calibration processes are described in the STSDAS Calibration Guide (16 April 1990). For WF/PC calibrated data the bias, preflash, and dark reference Files were obtained from laboratory testing of WF/PC prior to flight. The A to D correction was obtained from on-orbit data. The WF F555W and F439W flat fields were obtained from the average of observations of the sunlit earth. The NGC7457 observation was calibrated using an F547M flat field made on-orbit. The M15 observation was calibrated using laboratory flat field data. The flat fields are included on the tape. Users are cautioned that some of the keywords in the image headers are currently reported incorrectly. For FOC calibrated data the flat field and geometric reference files were obtained from laboratory measurements; these are in the process of being improved. For FOC we have included PSF examples. These exposures are not particularly long but do give a general impression of the FOC PSF at those two wavelengths. In all cases the reference files used for calibration purposes are provisional and liable to be significantly improved in the near future. (A major purpose of the Science Verification program starting soon is to derive good on-orbit reference data for calibration.) The original cover letter from Chris Blades (Telescope & Instruments Branch Chief) and Duccio Macchetto (Science Programs Division Head) is included in the file "HST_COVER_LETTER.TXT". This letter includes A full listing of the distribution tape. The data tape is in FITS format, 6250bpi, with a blocking factor of 10.
