v8.7.1

Main changes since v8.6.3:

  • A new subclass of Region called "Moc" has been added. A Moc describes an arbitrary region of the sky in the form of a set of HEALPix cells using the IVOA Multi-Order Coverage scheme. Version 1.1 of the the MOC recommendation is supported, including string and JSON encoded of MOCs.

  • A new subclass of Channel called "MocChan" has been added. This works with the Moc class to provide further options for reading and writing MOCs as strings.

  • The FitsChan class will now read FITS-WCS headers that have alternate axis descriptions but no primary axis descriptions.

  • The Region class has a new method called astGetRegionDisc, which returns the centre and radius of a disc that just encloses a 2-dimensional Region.

  • The Bounded attribute defined by the Region class is now always non-zero for Regions defined within a SkyFrame, regardless of whether the Region has been negated. Previously, it was non-zero only if the Region had not been negated. Note, this change only affects Regions defined within SkyFrames.
