contrast_curve
- jwst.coron.hlsp.contrast_curve(target_model, width)[source]
Compute “contrast curve” data for a PSF-subtracted image.
What’s computed is the 1-sigma noise in a series of concentric annuli centered at the geometric center of the image. The width of the annuli is set by the input argument “width”. A mask array is used iteratively to exclude all pixels outside of each annulus when the standard deviation is computed. Annuli are defined to the nearest pixel. No partial-pixel computations are performed.
- Parameters:
- target_model
ImageModel The science target data model
- widthfloat
Width of the annuli, in pixels
- target_model
- Returns:
- output_model
ContrastModel Data model with a table of radius and standard deviation of unmasked pixels
- output_model
