Description:
This recipe processes NOISE observations taken at various settings for the pixel heater
and detector bias. The noise properties are calculated over a given frequency range and
the resulting noise-equivalent power (NEP) data for each subarray are combined into a
4-d hypercube of the NEP as a function of bolometer position, heater and detector bias
value.
In addition the effective and weighted NEPs are calculated for each subarray and heater/bias
setting.
Details are written to log files: the noise properties are written to log.bolonoise as for regular noise
observations, while the NEPs are written to log.effnep and log.wtnep.
Notes:
Available Parameters :
The following parameters can be set via the
-recpars option:
NEP_MAX
Maximum NEP to be used in calculating the NEP images (W
Hz-0.5).
Default is 2.0e-14 W Hz-0.5.
NEP_MIN
Minimum NEP to be used in calculating the NEP images (W
Hz-0.5).
Default is 2.0e-17 W Hz-0.5.
NOISE_FREQRANGE
A pair of comma-separated values indicating the lower and upper frequency
bounds (in Hz) to be used in the calculation of the noise properties. Default is 2,10 Hz.
