Astronomical
Imaging Library
The following 5 sources will be used for future imaging simulations
(September 20, 2007).
These images are chosen for having the following properties:
- astronomical relevance
- high S/N dynamic range (>1000)
- high spatial dynamic range (>100)
All model images were once modified to have 1024 x 1024
pixels in order to run on the AIPS simulation package S. Heddle is
putting together. All images have 0.01" pixels. For lower resolution
simulations, comparisons should be made with convolved images
appropriate for the simulation observations.
Protoplanetary Disk
|
|
The original image was calculated in a numerical simulation by S. Wolf.
|
The model image (
SWOLF.MODEL) is 256 x 256 in size. It represents
a protoplanetary disk as simulated by Wolf and D'Angelo 2005.
It simulates a
M_planet = 1 M_jup around a star of M_star = 0.5 Msun
at a Distance = 50pc. A FITS model
image optimized for CASA use is available.
Protostellar Cluster
|
|
Model protostellar cluster, provided by K. Tatematsu.
The model image (not yet found; will be at
cluster.fits) has been used in previous ALMA simulations.

M51 in H alpha
|
|
This is a continuum subtracted H alpha image of the nearby
galaxy M51 (NGC 5194 -- provided by
D. Thilker at NRAO). This H alpha image should be a reasonable
representation of the atomic FIR lines and other tracers of
massive star formation, and it may be reasonable model for
other molecular transitions as well. Shown in logarithmic stretch.
Image dynamic range is
over 10000.
|
The model image (
M51HA.MODEL) is
512 x 512 pixels in size. Large negative pixels resulting from
subtraction of saturated stars have been blanked with 0's.
M31
|
|
This HII region in M31 displays complex extended structure.
|
A small model FITS image (
M31_128.FITS)is available. It was
1024 x 1024 pixels in size and had a pixel scale of 0.01 arcsecond
for the 3 km array simulation.
HCO+ J=4-3 line emission in a protostellar envelope
|
|
This is a model of the HCO+ 4-3 line emission in a protostellar envelope
provided by M. Hogerheijde. The model is viewed at inclination 60 degrees.
|
The model image (
HCO+_4-3_60.FITS) is 560 x 560 pixels in size.
Obvious image boundary structures
are also included, but we will treat it like any other structure in
the image.
