resample step has the following optional arguments that control
the behavior of the processing and the characteristics of the resampled
The fraction by which input pixels are “shrunk” before being drizzled onto the output image grid, given as a real number between 0 and 1.
The form of the kernel function used to distribute flux onto the output image. Available kernels are
Ratio of input to output pixel scale. A value of 0.5 means the output image would have 4 pixels sampling each input pixel.
The value to assign to output pixels that have zero weight or do not receive any flux from any input pixels during drizzling.
The weighting type for each input image. If
weight_type=exptime, the scaling value will be set equal to the exposure time found in the image header.
Blend metadata from all input images into the resampled output image.
Specifies the fractional amount of free memory to allow when creating the resampled image. If
None, the environmental variable
DMODEL_ALLOWED_MEMORYis used. If not defined, no check is made. If the resampled image would be larger than specified, an
OutputTooLargeErrorexception will be generated.
For example, if set to
0.5, only resampled images that use less than half the available memory can be created.
