ALMA calibration data are public from the time the observations are taken, but most calibration data is contained in EBs that also contain proprietary data. You may submit a Helpdesk ticket to your ARC to obtain the calibration data if you wish, and we will split it out from the EBs for you on a best-effort basis.
The extraction step of calibrator data will be automated at some point in the future so that no Helpdesk tickets are required any more.
