Preserve During Load

Scale - When a new image is load into the frame, existing scale parameters are preserved.
Pan - Preserve existing pan location when a new image is loaded into the frame.
Regions - All existing regions are preserved when a new image is loaded.

Save Image ...

Save current image as fits, jpeg, tiff, png, ppm, or mpeg file. Only the visible portion of the image is saved, along with all graphs including regions, catalogs, contours, and grids. If the image is a data cube, saving as a mpeg movie will generate a mpeg-1 movie, one frame per slice of data.

Save Frame as Fits...

Save the current frame as a fits image. This differs from above in that all image data is saved, not just the visible data. Also, no rotation, zoom, or panning is applied. The main purpose of this feature is to allow a user to load a FITS binary table, and save it as a FITS image.

Save Frames as MPEG...

Save all frames as a MPEG-1 movie. Each frame is cycled thru and the visible image is saved as one frame of the movie, along with all graphics including regions, catalogs, grids, and contours.

Display Fits Header

Displays the FITS header. If FITS Mosaic is loaded, a list of headers will be presented.. If FITS Bin Table is loaded, the table header will be displayed, not the binned image.
