fft_interp_norm
- jwst.refpix.irs2_subtract_reference.fft_interp_norm(dd0, mask0, row, hnorm, hnorm1, ny, ngroups, aa, n_iter_norm)[source]
Filter iteratively in FFT space of the normal pixels in each group.
- Parameters:
- dd0ndarray
Data array containing all groups, updated in place.
- mask0ndarray
Mask for pixels to filter, with dimensions ny x nrow. 1 means use the pixel, 0 means do not use it.
- rowint
Row size computed from the number of science pixels, reference pixels, and padding in an amplifier.
- hnormndarray
Array of column indices for normal pixels.
- hnorm1ndarray
Shifted index values for normal pixels.
- nyint
Y size of data array.
- ngroupsint
Number of groups.
- aandarray
Filter to apply.
- n_iter_normint
Number of filtering iterations.
