mocshape: Generates Multi-Order Coverage maps from shape values
mocshape takes a list of sky positions or shapes
from an input table and generates a Multi-Order Coverage map
(MOC)
that describes the union of their coverage on the sky.
It does a similar job to the older
pixfoot command,
but it can cope with input shapes that are more general than just points or
circles; it also understands polygons, STC-S strings and other MOC or UNIQ
specifications.
It is also implemented using some different and more flexible code.
It offers more output options for the calculated MOC via the
mocfmt parameter,
and a choice of MOC construction implementations via the mocimpl
parameter.
In most cases you can ignore this flexibility, but performance
characteristics may be different for the different choices,
and it may be worthwhile to experiment when working with very large tables.
