This is a relatively small dataset suitable for a quick demo.

The data is packaged with CASA, no need to download NGC5921 Demo Script (casapy script) NGC5921 Moment 0/1 Image (PNG 20KB) At right: Integrated VLA HI line intensity image (false color) with HI velocity field superposed (contours) for the galaxy NGC5921.

This is a larger dataset (the MS will be 5.2GB) and it will take longer to run (~40m) but produces a much nicer image.

NGC2403 data (tar-gzipped VLAExport 513MB) NGC2403 Tutorial Script (casapy script) NGC2403 Moment 0 Image (PNG 183KB) At right: Integrated VLA HI line intensity greyscale image (from moment zero map) of the galaxy NGC2403.

This is a 3mm CO line mosaic from the BIMA SONG survey (Helfer, Thornley, Regan, et al., 2003, ApJS, 145, 259).

NGC4826 data (tar-gzipped UVFITS 66MB) NGC4826 Tutorial Script (casapy script) NGC4826 Moment 1 Image (PNG 183KB) At right: False-color image of the CO velocity field (from a moment 1 image) for the BIMA SONG galaxy NGC4826.

This is a 3.6cm VLA continuum dataset taken in 1995 as follow up to the CLASS gravitational lens survey (S.T. Myers et al., 1995, ApJL, 447, L5). This is a small dataset suitable for quick demos.

B1608+656 VLA data (VLAExport 3.4MB) B1608+656 Demo Script (casapy script) B1608+656 3.6cm Image (PNG 31KB) At right: Continuum image of 4-image "quad" gravitational lens system CLASS B1608+656 from a 5-minute VLA 3.6cm snapshot.

This is a 6cm VLA continuum polarimetry dataset taken in 1999 as part of the VLA flux calibration test program.

Jupiter/FLUX99 VLA data (UVFITS 129MB) Jupiter Tutorial/Demo Script (casapy script) Jupiter 6cm Polarization Image (PNG 24KB) At right: Image of Jupiter 6cm intensity (false color) with polarized intensity (yellow contours) and polarization vectors (white, rotated 90deg to show B-field direction).

This is a larger dataset (the raw data is 107MB) and it will take longer to run (~40m). This combines B and C configuration data as 3C129 has a lot of large-scale emission. This makes a nice image.

3C129 data (tar-gzipped VLAExport 107MB) 3C129 Tutorial Script (casapy script) 3C129 Polarization Image (PNG 63KB) At right: Image of 3C129 6cm intensity (false color) with polarization vectors (white, rotated 90deg to show B-field direction).

This is a SMA dataset with a large number of spectral channels.

SMA data (tar UVFITS 891MB) SMA example script (casapy script) SMA on Spitzer Image (PNG 60KB) At right: Spitzer GLIMPSE 8 um image with green contours showing the integrated CO(2-1) emission from SMA for infrared dark cloud G19.3+0.07 (Brogan et al. in prep).
