Flip and Reproject Operation

At the telescope, it is often useful to see the sky map in mirror image. When the flip option is selected, the images will be displayed with North up and East to the right. This is purely for presentation; the underlying FITS images are not modified.

The reproject operation resamples each image to the same orientation (North up), pixel scale (0.36 arcsec), and WCS projection type (Gnomonic TAN), the reprojected images maintain exact photometry.
