Functions

int cpl_plugin_get_info (cpl_pluginlist *list)
 Build the list of available plugins, for this module.
int omega_readnoise_save (cpl_frameset *set, cpl_parameterlist *parlist)
 Save the omega_readnoise recipe products on disk.

Detailed Description

Synopsis:
Calculate the read noise of the detector. The read_noise is computed by subtracting two raw bias images,
and dividing the standard deviation by sqrt(2). The statistics of the difference between the raw biases is
computed iteratively. Bad pixels are rejected if they differ more than process_params.REJECTION_THRESHOLD
sigma from the median. The maximum number of iteration is process_params.MAXIMUM_ITERATIONS. The recipes
expects the following tags in the set of frames:
Input frames:
BIAS_READNOISE
Output frames:
READNOISE_ADU
