class subpixal.resample.Resample(config=None, **kwargs)

An abstract class providing interface for resampling and combining sets of images onto a rectified frame.

property computed_sky

abstract execute(self)

Run resampling algorithm.

abstract fast_add_image(self, add_file_name)

Re-calculate resampled image using all input images and adding another image to the list of input images specified by the add_file_name parameter.

Parameters

add_file_namestr

File name of the image to be added to the input image list when re-calculating the resampled image.

abstract fast_drop_image(self, drop_file_name)

Re-calculate resampled image using all input images other than the one specified by drop_file_name.

Parameters

drop_file_namestr

File name of the image to be dropped from the list of input images when re-calculating the resampled image.

property input_image_names

Get an OrderedDict of input file names and image extensions or None.

property output_crclean

Get file names of the Cosmic Ray (CR) cleaned images (if any).

property output_ctx

Get output file name for context data file or None.

property output_sci

Get output file name for output science image or None.

property output_wht

Get output file name for output weight image or None.

abstract property reference_image

Get/Set Reference image. When reference_image is None, output WCS and grid are computed automatically.

abstract set_config_parameters(self, **kwargs)

Override individual configuration parameters.

class subpixal.resample.Drizzle(config=None, **kwargs)

execute(self)

Run resampling algorithm.

fast_add_image(self, add_file_name)

Re-calculate resampled image using all input images and adding another image to the list of input images specified by the add_file_name parameter.

Parameters

add_file_namestr

File name of the image to be added to the input image list when re-calculating the resampled image.

fast_drop_image(self, drop_file_name)

Re-calculate resampled image using all input images other than the one specified by drop_file_name.

Parameters

drop_file_namestr

File name of the image to be dropped from the list of input images when re-calculating the resampled image.

fast_replace_image(self, drop_file_name, add_file_name)

Re-calculate resampled image using all input images and adding another image to the list of input images specified by the add_file_name parameter.

Parameters

add_file_namestr

File name of the image to be added to the input image list when re-calculating the resampled image.

property reference_image

Get/Set Reference image. When reference_image is None, output WCS and grid are computed automatically.

set_config(self, config=None, **kwargs)

set_config_parameters(self, **kwargs)

Override individual configuration parameters.
