The kmo_noise_map recipe

kmo_noise_map

Synopsis

Generate a noise map from a raw frame

Description

The noise in each pixel of the input data is estimated using gain and readnoise.

The readnoise is expected to be in the primary header (ESO DET CHIP RON), the gain (ESO DET CHIP GAIN) has to be in each of the subsequent headers of each detector frame. The output is the initial noise map of the data frame.
