1.0

Version 1.0 is finally there! Changes from 0.7 are minor, and mostly target the continuous integration:

• Added boresight pointing and polarization angle systematics capabilities into the tod code, and updated flat-sky saving routine for IGQU deprojections (#42 )
• CI: move from travis to to GH Actions (#45, #47, #54 )
• Improve code quality (#52 )
• Bug fix (#50 )

Thanks @markm42 for contributing !

0.6.1

• Add Neil small aperture scan
• Add method to perform systematic deprojection (IGQU)
• Add App for differential pointing
• Fix bug in dealing with leap second correction.
• Allow python 3.5 & 3.6 (both code and Travis fixed)
• Allow image in interactive ipython to be shown
• Completely remove weave - never used in practice (use fortran instead for speed-up)

0.6.0

• Add HWP demodulation (in addition to pair difference) to estimate I, Q, and U from timestreams.
• Allow different nside (input vs output) to be used.

0.5.3

• Add ACT scanning strategy, and custom scanning strategy.
• Add link to the bootcamp in the description (https://github.com/JulienPeloton/s4cmb-resources).

0.5.2

• Improve coverage and coverage tool.
• Simplify the scanning strategy module.
• Add App to study relative gain variation
• Allow to process channel-by-channel in tod2map to save memory!
• Update the default noise level to 5ish uk.arcmin.
• Add routines to simulate gain drifts.

0.5.1

• Fix bug in bolometer coordinates in the focal plane (it was mixed with pair coordinates).
• Allow routine in HealpixFitsMap to read alms files directly.
• Allow the mapping per detector pair to save memory.
• Remove the notebooks from the repo (now at https://github.com/JulienPeloton/s4cmb_notebooks).
• Add new routines to simulate differential pointing.
• Add new routines to define detectors gain.

0.5.0

• Include flat sky projection for the output maps.
• Include white noise simulator (time-domain noise).
• Include Dockerfile.

0.4.0

• Add examples for MPI usage (with examples on Cori, NERSC).
• Add fits interface for dumping maps on disk.
• Remove unused args in several classes and routines.
• Add App for SO, and support for xpure.
• Massive change in the way parsers are handled.
• Add SQUID to SQUID crosstalk.
