5.6.17    Mosaic Modules: Mosaic Reinterpolate

Command Line Equivalent: run_mosaic_reint

Default Output Directory: <output_dir>/Reinterp-mosaic

Depends On: Mosaic Interpolate; Mosaic RMask

 

PURPOSE

This module runs the interpolation again using the RMasks. Only pixels flagged by the RMasks are re-interpolated.

 

INPUT

Mosaic Reinterpolate output subdirectory: The subdirectory of <output_dir> that you wish to use for the output files. Default is Reinterp-mosaic.

 

COMMAND LINE INPUT

&MOSAICREINTIN

&END

In Global Parameters:

REINTERP_DIR = Reinterp-mosaic

 

OUTPUT

ReInterp Stack (interp_*.fits): The new interpolated image stack, with Rmask-flagged pixels having been updated.

 

ReInterp coverage (interp_*covg.fits): The corresponding coverage map for each interpolated image in the stack.

 

ReInterp Sigma (interp_unc_*sigma.fits): The corresponding uncertainty files for each image in the stack.

 

DISCUSSION

Warning: Do not use this module when using the Drizzle or GRID interpolation schemes in the Mosaic Interpolate Module. See §5.6.8: Mosaic Interpolate for more information.

 

The process of reinterpolation is performed after the various outlier masks are combined into the RMasks by the Mosaic RMask module. Only the pixels masked in the RMask images are recomputed, which makes it much faster than doing interpolation from scratch again.

 

Reinterpolation uses the same interpolation scheme and other processing parameters as used by the original interpolation. All this information is recorded in the headers of the interpolated images. The newly interpolated images become the input to later modules.
