New ALMA Memo on Design and Implementation of the wvrgcal Program

We have published a new memo in the ALMA Memo Series, “Design and Implementation of the wvrgcal Program”. The PDF is available here at

The abstract is:

This memo describes the software engineering and technical details of the design and implementation of the wvrgcal program and associated libraries. This program performs off-line correction of atmospheric phase fluctuations in ALMA observations, using the 183 GHz Water Vapour Radiometers (WVRs) installed on the ALMA 12m dishes. The memo can be used as a guide for detailed study of the source code of the program for purposes of further development or maintenance.
