Pull request overview
Fixes CoDICE L2 intensity/geometric-factor calculations to properly handle invalid (fill-valued) half_spin_per_esa_step entries, preventing incorrect mode/assignment behavior when the LUT data is padded or masked.
Changes:
- Introduces a shared
HALF_SPIN_FILLVALconstant (63) forhalf_spin_per_esa_stepinvalid values. - Updates L2 geometric factor mode selection and LO angular intensity A/B indexing to ignore fill-valued half-spin steps.
- Updates LO L1A products to pad and mask
half_spin_per_esa_stepusing the fill value instead ofNaN/literal63.

Looks good to me. Just a couple of things.

Change Summary
Overview
I ran a final check on dec 28th data and noticed a bug where we are not checking whether the half_spin_per_esa step is valid in l2 computations that use this variable.
