_GET_GAIN_

Finds the LCO instrument gain in electrons per ADU for the current Frame

Description:

This primitive obtains the gain in electrons per ADU for the current frame. It first attempts to find a value from the ORAC_GAIN header. If this is null or less than 3.0, the primitive uses a time-dependent default value, and it reports the use of the default.

The gain is returned through an argument.
