Detailed Description

An interface to an astrometry.net catalog

Behaves like a list of MultiIndexCache (or multiindex_t).

These should usually be constructed using the 'fromEnvironment'
class method, which wraps the 'fromIndexFiles' and 'fromCache'
alternative class methods.

◆ writeCache()

def lsst.meas.extensions.astrometryNet.multiindex.AstrometryNetCatalog.writeCache (   self)
Write a cache file

The cache file is a FITS file with all the required information to
build the AstrometryNetCatalog quickly.  The first table extension
contains a row for each multiindex, storing the healpix and nside
values.  The second table extension contains a row for each filename
in all the multiindexes.  The two may be JOINed through the 'id'
column.
