NAME

astmoctool - Utility for manipulating MOC files using AST

USAGE

Command line options are processed in the order given. These can either be the names of files to read, or options giving other operations to perform. For example to load a file and then display information:

astmoctool MOC.fits --info

Note: AST performs all MOC operations at a particular "MaxOrder" value. This will be determined by the first loaded MOC or can be specified via the "--max-order" option. Cells smaller than this order are ignored.

OPTIONS

--info

Display information about the current MOC.

--output FILENAME

Write the current MOC to the given file.

--intersection FILENAME

Perform an intersection between the current MOC and the MOC in the given file.

--subtract FILENAME

Subtract the MOC in the given file from the current MOC.

--show

Display a description of the current AST MOC object.

--max-order

Set the maximum order. This must be done before any MOC is loaded.
