pypeit/PypeIt: Version 1.8.0

Significant changes

• Code to allow for mosaicing multiple detectors into a single reduction. This is now the default for Gemini GMOS and improves stability of wavelength calibration.
• Introduces pypeit_parse_calib_id script
• Refactored manual extraction
• Update for LDT/DeVeny including support for binned data, use_header for reading arc lamps used from frames, and reid_arxiv templates for three additional gratings.
• Slurps in and uses slitmask design for Keck/LRIS (limited usage)
• Significant improvements in 2D coadding.
• Scripts to explore the noise residuals in PypeIt

• Improved performance of L.A. Cosmic implementation
• Now uses stars in alignment boxes for default calculation of slitmask offsets in DEIMOS reductions.
• 2D wavelength calibration image now added to MasterFlat output
• Improved treatment of saturation.
• Dark counts used for calculating the shot noise now includes measured dark images if provided.
• Include sky model in 2nd pass of global sky subtraction (not for IR redux).
• Skymask is now computed also for the maskdef_extract objects.
• Added dedicated fwhm and boxcar_radius for maskdef_extract objects.
• Added pypeit_version to the pypeit file header.
• Set DEIMOS find_fwhm default to 0.8" in binned pixels.
• Added row-dependent pattern-noise calculation for KCWI

• Fixed a bug about how maskdef_offset is assigned to each detector
• Fixed 2Dcoadd spec bugs for central wavelength dithers.
