All notable changes to this project will be documented in this file.
The format is based on Keep a Changelog, and this project, at least loosely, adheres to Semantic Versioning.
- Added computation of other Kopeikin solutions (
solutions = model.alternative_solutions()) - Added computation of extra parameters in gridding
- Added gridding based on tuples of parameters (not just regular mesh)
- Added passing of extra parameters to gridding fitter
- Added option to photonphase to compute phases using polycos
- New
colorize()function inpint.utilswhich can be used for string and unicode output - Split out get_derived_params() from get_summary() in fitter.py. Can be used other places.
pintkcan now automatically select the right fitter, and can otherwise specify fitter from the command-line or a dropdown- automatic fitter selection available with standard API as well
- added tempo(2) par/tim output to
pintk - added icon to
pintk
- Huge number of bugs and improvements to
pintk, and some topintempo - Multiple bug fixes in get_summary()/get_derived_params(), especially for binary calculations

- Changed logging to use
loguru - Changed to floating point format and added color for correlation matrix output

time_gbt.dat) and GPS to UTC conversion (gps2utc.clk) with new entries
