Changes for 2.0.0:

Added

• The NEAR MSI driver now emits the single-parameter radial optical distortion (from the INS<ikid>_K1 coefficient) that ISIS models, and subtracts 0.5 from the detector center to match the ISIS 0.5-based detector-coordinate convention. The resulting CSM camera agrees with the ISIS camera to sub-pixel (cam_test pixel difference drops from ~0.7 px to ~1e-8 px on a real NEAR MSI image). #740
• The Clementine NIR camera now emits the single-parameter radial optical distortion (k1 = -0.0006364, as in the ISIS NirCamera + RadialDistortionMap) that ISIS models, and subtracts 0.5 from its detector center to match the ISIS 0.5-based detector-coordinate convention. The resulting CSM camera agrees with the ISIS camera to sub-pixel (cam_test pixel difference drops from ~1.2 px median, ~6 px max to ~1e-7 px on a real Clementine NIR image). The UVVIS, HiRes and LWIR Clementine cameras are unchanged; only NIR is modeled here. #740
• Quaternion reduction based on the naif spice fortran routine ck3sdn. This uses a tolerance to reduce the number of quaternions for ISDs that don't extract the exact CK times from the kernels. #747

Fixed

• The installed CMake package config now finds its nlohmann_json dependency, so find_package(ale) works without a prior find_package(nlohmann_json). #748
• Fixed MEX HRSC SRC detector center to match latest IAK. #753
• Fixed Messenger MDIS to include Taylor distortion to match ISIS' implementation. #757
• evaluateCubicHermiteFirstDeriv now checks that y has as many points as the derivatives and times, instead of reading past the end of y. #749
• Cassini ISS drivers now produce a CSM camera that matches ISIS (ASP cam_test on a NAC image shows the ISIS-SPICE, NAIF-SPICE and PDS3 drivers agree with ISIS to ~5e-4 px). Fixes:
  • ISIS-SPICE driver: emit the radial optical distortion (was none).
  • ISIS-SPICE and NAIF-SPICE drivers: subtract 0.5 from the detector center (ISIS 0.5-based to CSM 0-based).
  • NAIF-SPICE driver: focal_length no longer raises AttributeError when INS_FOCAL_LENGTH is defined.
  • NAIF-SPICE driver: ephemeris_start_time uses the scalar from utcToEt (was a tuple). #739
• isd_generate now fails with an error instead of writing an ISD with null required fields. #754
• Fixed kernel quality check to allow quality keys from different missions #758

Changed

• isd_generate: default --reduction to linear (sampling every 10th line for line-scan images with >= 1000 lines). This avoids creating oversized ISDs (tens of thousands of pose samples) for long line-scan sensors such as LRO NAC, MRO CTX, and HRSC. Pass --reduction none to disable reduction and restore per-line sampling. #744

Removed

• Removed isis_formatter and usgscsm_formatter. Ale formatter will always be used. #737
