+=== Side note on astrometry ===
+
+we were having trouble with astrometry in May.  I've been looking into this a bit more, and it looks like at least part of the problem is that the angle moves around a bit, and the solution is sensitive to angles of 1-2 degrees.  The file ippconfig/vysos5/psastro.config includes an option for searching over a range of angles (PSASTRO.GRID.MIN.ANGLE, PSASTRO.GRID.MAX.ANGLE, PSASTRO.GRID.DEL.ANGLE).  I've set this to -10 to +10 in steps of 1 degree.  This may not be enough range in some cases.
