Binary package “weightwatcher” in ubuntu oracular
Combine maps and polygon data for astronomical image processing
WeightWatcher is a program that combines weight-maps, flag-maps and polygon
data in order to produce control maps which can directly be used in
astronomical image-processing packages like Drizzle, Swarp or SExtractor.

Weight-
WeightWatcher through a configuration file: this alleviates other programs
from such interpretation work. WeightWatcher will mostly be useful as part of
an imaging survey pipeline. Its main features are:
.
* Processing speed: limited by the I/O performances of the machine
(typically 50 Mpixel/s on a workstation),
* Ability to work with very large images (up to, say, 10^8 × 10^9 pixels on
a 64 bit system),
* FITS format (including Multi-Extension) is used for input and
output. Output flag-map format selection is automatic (8, 16 or 32bits),
* Up to 30 weight-maps, 30 flag-maps, and thousands of polygons can be
handled simultaneously.
* Automatic rasterizing of DS9 .reg files,
* Statistics of flagged and weighted areas,
* Metadata output in XML-VOTable format.
