WMAP-LX software suite was developed to reproduce the original iterative calibration pipeline used by the WMAP team to calibrate the time ordered data (TOD).
It consists of several parts. The calibration application itself is written in C++ and can be compiled by both GCC and MSVC. Data extractions and map plotting routines are in IDL. Map-making is done by IDL map-making software by Hao Liu and Ti-Pei Li (arXiv:0907.2731v3) and calibration result analysis routines are in MATLAB.
A discussion of the calibration performance and the first scientific results are available in Testing Robustness of WMAP Temperature Calibration to Timing Offsets.
