autocti.ImagingCI#

class autocti.ImagingCI(data: Array2D, noise_map: Array2D, pre_cti_data: Array2D, layout: Layout2DCI, cosmic_ray_map: Optional[Array2D] = None, noise_scaling_map_dict: Optional[Dict] = None, fpr_value: Optional[float] = None, settings_dict: Optional[Dict] = None)[source]#

A class containing an imaging dataset, including the image data, noise-map and a point spread function (PSF).

Parameters:

  • data – The array of the image data, for example in units of electrons per second.

  • noise_map – An array describing the RMS standard deviation error in each pixel, for example in units of electrons per second.

  • psf – An array describing the Point Spread Function kernel of the image which accounts for diffraction due to the telescope optics via 2D convolution.

  • settings – Controls settings of how the dataset is set up (e.g. the types of grids used to perform calculations).

Methods

__init__(data, noise_map, pre_cti_data, layout)

A class containing an imaging dataset, including the image data, noise-map and a point spread function (PSF).

apply_mask(mask)

Apply a mask to the imaging dataset, whereby the mask is applied to the image data, noise-map and other quantities one-by-one.

apply_settings(settings)

Returns a new instance of the imaging with the input SettingsImaging applied to them.

from_fits(layout, pixel_scales[, data_path, ...])

Factory for loading the imaging data_type from .fits files, as well as computing properties like the noise-map, exposure-time map, etc.

output_to_fits(data_path[, noise_map_path, ...])

set_noise_scaling_map_dict(...)

trimmed_after_convolution_from(kernel_shape)
