Getting Started

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.

AIPSCASA Purpose
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.
