REDUCE_NOISE

Process NOISE observations

Description:

The recipe calculates the average power spectrum for each array, displaying each in a separate window, before calculating the white noise properties (and noise equivalent power). The noise properties are written to a log file, log.bolonoise. The array mapping speed is calculated and written to a log file called log.mapspeed_SUBARRAY.

The results are displayed in a Kapview window.

Notes:

Available Parameters :

The following parameters can be set via the -recpars option:
RESIST_CFG
Name of an alternative list of resistor values used when calculating the flatfield. File must be in ORAC_DATA_OUT.

Display

One Kapview window is used to display the average power spectra for each subarray. The focal-plane noise map and histogram are shown in a separate Kapview window, along with maps of the NEP and the percentage-change in the noise.
