ALMA WVR phase correction algorithms and softwareТЖ

WVRGCALТЖ

wvrgcal is a command line front end to LibAIR (see below) and is the user-facing application for calculating atmospheric phase correction from WVR data. wvrgcal outputs a CASA gain calibration table which can then be applied to the observed data in the usual way.

Download binary packagesТЖ

Please note these binary packages are offered on an experimental basis, under the GPL license, with no warranty of any kind. By their nature, binary packages work only on a restricted class of systems similar to the ones they were built on. For some notes on installation see this message.

The binary packages are now built in both 32 and 64bit versions, but for the present time still for Linux only. The 32bit version have the string “x86” at the end of their name and the 64bit version has the string “x64” string at the end of their name. These strings unfortunately look quite similar to the eye, so be careful! (These are the standard platform names so that is why they are used)

User instructionТЖ

For instructions on use of this program see: http://wikis.alma.cl/bin/view/AIV/Application

Source codeТЖ

The source code for the wvrgcal program is included in the packages below.

LibAIRТЖ

LibAIR is the atmospheric inference library that is the main core of the algorithms for phase correction of ALMA data using water vapour radiometers that we are developing in Cambridge. You can download, use and reuse the libAIR code under the LGPL license.

The library and algorithms are documented in the series of memo’s which are being posted at page on inference of coefficients for use in phase correction.
