Aliases Required By Specific Processes
The following table lists the aliases that have to be set in order to run specific processes for processing airborne gamma-ray data. Note how the "output fields" become the "input fields" for subsequent processes – so the processes must be run in a specific order! See Tutorial 1 – Processing Airborne Data for the sequence of processing steps.

"base_up" "gain_up" |
The "base_up" and "gain_up" database fields names are pre-set by GammaSpec |
