kmo_noise_map - Generate a noise map from a raw frame


esorex kmo_noise_map [OPTIONS] FILE.sof


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.

Input files:

category Type Explanation Required #Frames
-------- ----- ----------- -------- -------
<none or any> RAW raw data frame Y 1

Output files:

category Type Explanation
-------- ----- -----------
NOISE_MAP F2D Initial noise map
(6 Extensions, 3 data and 3 noise)


Note that it is possible to create a configuration file containing these options, along with suitable default values. Please refer to the details provided by the 'esorex --help' command.

Basic documentation about the EsoRex program can be found at the esorex (1) man page.

It is possible to call the pipelines from python using the python-cpl package. See for further information.
