This section describes the motivation, background, and process for calibrating ALMA single-dish observations.

Below are brief descriptions of the calibration process, followed by a description of the various observing modes, and then a step-by-step description of the calibration process in CASA.

It is recommended that newcomers review the description of calibration in Single-dish calibration: background and descriptions of various observing modes in Single-dish observing modes before examining the reduction processes decribed in Single-dish data calibration and reduction. Future directions are broadly outlined in Future development goals for CASA single-dish.
