pynrc.simul.ngNRC.apply_flat(cube, det, imflat_full)[source]

Apply flat field

Includes pixel-to-pixel QE variations or instrument’s optical flatfield (e.g., throughput variations across the field).

Parameters:

cube (ndarray) – Simulated ramp data in e-. These should be intrinsic flux values with Poisson noise, but prior to read noise, kTC, IPC, etc. Size (nz,ny,nx). In ‘det’ coords. Can either be full frame or match det subarray. Returns det subarray shape.
det (Detector Class) – Desired detector class output. Mainly just utilizes detector subarray position and shape.
imflat_full (ndarray) – Full field image of flat field in det coords. Will get trimmed if necessary.
