autocti.Clocker1D#

class autocti.Clocker1D(iterations: int = 5, roe: Optional[ROE] = None, express: int = 0, window_start: int = 0, window_stop: int = -1, time_start=0, time_stop=-1, prune_n_electrons=1e-18, prune_frequency=20, allow_negative_pixels=1, verbosity: int = 0)[source]#

Performs clocking of a 1D signal via the c++ arctic algorithm.

This corresponds to a single row or column of a CCD in the parallel or serial direction. Given the notion of parallel and serial are not relevent in 1D, these prefixes are dropped from parameters (unlike the Clocker2D) object.

Parameters:

  • iterations – The number of iterations used to correct CTI from an image.

  • roe – Contains parameters describing the read-out electronics of the CCD (e.g. CCD dwell times, charge injection clocking, etc.).

  • express – An integer factor describing how pixel-to-pixel transfers are combined into single transfers for efficiency (see: https://academic.oup.com/mnras/article/401/1/371/1006825).

  • window_start – The pixel index of the input image where arCTIc clocking begins, for example if window_start=10 the first 10 pixels are omitted and not clocked.

  • window_start – The pixel index of the input image where arCTIc clocking ends, for example if window_start=20 any pixels after the 20th pixel are omitted and not clocked.

  • verbosity – Whether to silence print statements and output from the c++ arctic call.
