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.
Below are links to the relevant training materials and session info:
CASA tutorial in Santiago January 2009:
On January 26-27 2009 we held CASA tutorials in Santiago
aimed at introducing new JAO staff and astronomers from nearby
institutions to CASA.
CASA AOC Tutorial October 2008:
On October 7, 2008, we held a CASA Tutorial at
the AOC in Socorro, New Mexico, aimed at further introducing CASA
to local staff.
2008 Synthesis Imaging Workshop:
On June 13, 2008, we held CASA Tutorials
for participants of the 11th Synthesis Imaging Workshop.
Two tutorials focused
on VLA centimeter data (continuum and spectral line), a third on
BIMA millimeter data.
CASA AOC Tutorial December 2007:
On December 4, 2007, we held a CASA Tutorial at
the AOC in Socorro, New Mexico. This 1-day camp was aimed at
introducing the NRAO staff to CASA.
CASA Camp October 2007:
From October 16-18 we held a CASA Training Boot Camp in
Socorro, New Mexico. This intensive 3-day camp was aimed at training
the first cadre of CASA User Support Specialists.
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:
VLA HI Line Data (NGC2403)
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.

BIMA CO Line Data (NGC4826)
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.

VLA 3.6cm Continuum (CLASS B1608+656)
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.

VLA 6cm Continuum Polarization (Jupiter)
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).
|

VLA 6cm Continuum Polarimetry (3C129)
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.
CASA Documentation and Help
There are a number of reference documents and help facilities
available to the user:
- The current Beta Release Edition of the
CASA Data Analysis Cookbook (PDF) is a how-to manual aimed at scientific
users. The Cookbook also contains a description of what is
available in the Beta Release (look for the Beta Alert notices
within).
- There is extensive in-line help for tasks inside CASA, just
type " help < taskname >". This information
is also available online in the
CASA Task Reference.
- The
CASA Toolkit Manual goes into more detail on the use of
the CASA Toolkit.
- There is a set of
Beta Release Notes that contain a list of key features and
"gotchas" for potential users.
- The Beta Release FAQ
has a list of known problems that users should take a look at
if they are encountering issues.
- There is a quick-reference
Getting Started guide.
- There is a wiki site for the
ALMA Simulator Documentation (the almasimmos task).
- Registered NRAO Interactive Services users can access the CASA HelpDesk
through the my.nrao.edu portal
(use the CASA Beta Release tab and then the Helpdesk sub-tab).
- For internal NRAO and ALMA/EVLA project users, CASA uses
JIRA as its issue tracking
system. Registered NRAO JIRA users can submit issues and maintain
contact with CASA until resolution.
Please send any comments or questions about CASA
to casa-request@nrao.edu
