  5 8a3b2ceb 2004-04-24 devnull  *		of prior implementations.
  6 8a3b2ceb 2004-04-24 devnull  *
  7 8a3b2ceb 2004-04-24 devnull  *	Keys:
  8 8a3b2ceb 2004-04-24 devnull  *		32 bits long. High 26 bits are encoded as described below.
  9 8a3b2ceb 2004-04-24 devnull  *		Low 6 bits are types:
 10 8a3b2ceb 2004-04-24 devnull  *
 11 8a3b2ceb 2004-04-24 devnull  *		Patch is ~ one square degree of sky.  It points to an otherwise
 12 8a3b2ceb 2004-04-24 devnull  *			anonymous list of Catalog keys.  The 0th key is special:
 13 8a3b2ceb 2004-04-24 devnull  *			it contains up to 4 constellation identifiers.
 14 8a3b2ceb 2004-04-24 devnull  *		Catalogs (SAO,NGC,M,...) are:
 15 8a3b2ceb 2004-04-24 devnull  *			31.........8|76|543210
 16 8a3b2ceb 2004-04-24 devnull  *			  catalog # |BB|catalog name
 17 8a3b2ceb 2004-04-24 devnull  *			BB is two bits of brightness:
 18 8a3b2ceb 2004-04-24 devnull  *				00	-inf <  m <=  7
 19 8a3b2ceb 2004-04-24 devnull  *				01	   7 <  m <= 10

 21 8a3b2ceb 2004-04-24 devnull  *				11	  13 <  m <  inf
 22 8a3b2ceb 2004-04-24 devnull  *			The BB field is a dreg, and correct only for SAO and NGC.
 23 8a3b2ceb 2004-04-24 devnull  *			IC(n) is just NGC(n+7840)
 24 8a3b2ceb 2004-04-24 devnull  *		Others should be self-explanatory.
