Montage Viewer: Miscellaneous Directives
There are couple of additional mViewer directives that can be useful under unusual circumstances:
- -nowcs The FITS file has no WCS information, which means we cannot perform
any coordinate-base operations. Nevertheless we still wish to generate a PNG/JPEG
of the data array.
- -noflip mViewer analyzes parameters like CDELT and CROTA and flips axes to
put North as close to up and East as close to left as is possible without real rotation.
Sometimes we want to override this logic.
