[cordellmichaud]

Description

Added a units label of "W/m2/sr/um" to the RadiometricType keyword in the output cube of lrowaccal.

Related Issue

N/A

Motivation and Context

This change adds the radiance units label for the output cube of lrowaccal as suggested by the LROC science team to more clearly indicate the radiance units and to accompany a change to the radiance calibration coefficients to make the radiance units match those of the NAC.

How Has This Been Tested?

The change was tested and validated by the science team at LROC, alongside the change to the radiance calibration coefficients.
