For AIPS users who are learning CASA, it is intuitive to think about equivalent tasks between the two software packages. Below are some AIPS-to-CASA equivalent tasks; note that there is not always a one-to-one transformation between the two packages.

| BLCHN | blcal | Calculate a baseline-based bandpass calibration solution |
| BPASS | bandpass | Calibrate bandpasses |
| CALIB | gaincal | Calibrate gains (amplitudes and phases) |
| CLCAL | applycal | Apply calibration to data |
| COMB | immath | Combine images |
| CPASS | cpass | Calibrate bandpasses by polynomial fitting |
