NAME
amsu.amsua.limbcorrection.AMSUALimbCorrection.java
PURPOSE
To adjust a satellite observation to nadir sensor incidence angle (limb correction).
DESCRIPTION
This class is the entry point for limb correction both for level 1c processing (if limb correction flag is set) and level 3 processing (if limb correction flag is set). It specifies current limb correction scheme used, loads coefficients from files, and adjusts satellite observations to nadir.
