+ Frequently astronomical survey catalogues or images are sparse and
+ cover only a small part of the sky. In a Multi-Order Coverage map
+ the extent of data in a particular dataset is cached as a
+ pre-calculated mask image. The hierarchical nature enables fast
+ boolean operations in image space, without needing to perform complex
+ geometrical calculations. Services such as VizieR generally offer the
+ MOC masks, allowing a faster experience in graphical applications
+ such as Aladin, or for researchers quickly needing to locate which
+ datasets may contain overlapping coverage.
+
+ The MOC mask image itself is tessellated and stored in NASA HealPix
+ format, encoded inside a FITS image container. Using the HealPix
+ (Hierarchical Equal Area isoLatitude Pixelization) tessellation
+ method ensures that more precision (pixels) in the mask are available
+ when describing complex shapes such as approximating survey or
+ polygon edges, while only needing to store a single big cell/pixel
+ when an coverage is either completely inside, or outside of the mask.
+ Catalogues can be rendered on the mask as circles.
