The primer (or "cheat sheet") is intended to help those VLBA users who are used to calibrating and imaging their data in AIPS transition to CASA.
It presents the AIPS VLBAUTIL procedures, the AIPS task(s) associated with those procedures, and the equivalent CASA task(s) and/or tool(s).
Loading Data
Both AIPS and CASA need to take the FITS-IDI file and convert it into a format they can use. AIPS uses the UVDATA format, and CASA uses the Measurement Set (MS) format.
| VLBAUTIL Procedure | AIPS Task(s) | CASA Task(s) |
|---|---|---|
| VLBALOAD | FITLD | importfitsidi |
Observation Summary
Printing a summary of the observation is often useful for identifying the fringe finder, bandpass calibrator, phase reference calibrator, and science target. It is also useful for locating a good time range to use for the instrumental delay correction.
| VLBAUTIL Procedure | AIPS Task(s) | CASA Task(s) |
|---|---|---|
| VLBASUMM | PRTAN | listobs |
| LISTR optype 'scan' |
