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.

|---|---|---|
| BLCAL | blcal | Calibrate amplitudes and phases in a baseline-based fashion. |
| 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 |
| DBCON | concat | Concatenate uv datasets |
| DEFAULT | default | Load a task with default parameters |
| FILLM | importvla | Import old-format VLA data |
| FITLD | importuvfits | Import a uv dataset which is in FITS format |
| FITLD | importfits | Import an image which is in FITS format |
| FITTP | exportuvfits | Write a uv dataset to FITS format |
| FITTP | exportfits | Write an image to FITS format |
| FRING | --- | Calibrate group delays and phase rates. |

| LISTR | LISTOBS | Print basic data |
| MCAT | LS | List image data files |
| MOMNT | IMMOMENTS | Compute moments from an image |
| OHGEO | IMREGRID | Regrids an image onto another image's geometry |
| PBCOR | IMMATH | Correct an image for the primary beam |
| PCAL | POLCAL | Calibrate polarization |
