### ENG_NEP

Process NEP measurements made in engineering mode

#### 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:

• Not designed to run in real time.

• Bias ramp data are ignored.

#### Available Parameters :

##### NEP_MAX
Maximum NEP to be used in calculating the NEP images (W Hz$\ast$$\ast$-0.5). Default is 2.0e-14 W Hz$\ast$$\ast$-0.5.
##### NEP_MIN
Minimum NEP to be used in calculating the NEP images (W Hz$\ast$$\ast$-0.5). Default is 2.0e-17 W Hz$\ast$$\ast$-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.
