CASA Scripts and Data
As part of our testing and training programs, we have developed a
number of "use case" and "demo" scripts. Here are links to a
selection of these:
This is a relatively small dataset suitable for a quick demo.
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.
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).
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.
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.
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.
At right: Image of 3C129 6cm intensity (false color) with polarization vectors (white, rotated 90deg to show B-field direction). |

For Experienced Users: CASA Scripts and Data
Here are some more data and scripts, intended for more experienced
CASA users and exploring more technical uses of the package. These
scripts are not generally set up as demos or tutorials, and users will
likely need to read through them carefully and in some cases
cut-and-paste commands to their casapy session.
This is a SMA dataset with a large number of spectral channels.
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).
CASA Training Materials
We have held a number of training sessions for CASA. We intend
to archive the materials here for use online for training, and for
building new training sessions. These are available from the
CASA Training Page
CASA Documentation and Help
There are a number of reference documents and help facilities
available to the user, for more information, see the
Help and Documentation page.
