 <h3> Elixir Configuration Data </h3>
 
+Mosastro uses the following Elixir configuration variables:
 
+<ul>
+<li> EXPTIME-KEYWORD  : header keyword defining exposure time
+<li> DATE-KEYWORD  : header keyword defining the date 
+<li> DATE-MODE  : mode for header date information: use a combination
+of Ys, Ms, Ds to specify order.  If only 2 digits are specified for
+the year, numbers greater than 50 are assumed in the 1900s, less than
+in the 2000s.  eg YYYY/MM/DD
+<li> UT-KEYWORD  : header keyword defining UT
+<li> MJD-KEYWORD  : header keyword defining MJD
+<li> JD-KEYWORD  : header keyword defining JD
+
+note that only one of the combination JD, MJD, or DATE/UT needs to be
+defined. 
+
+<li> ASTRO_REFCAT  : desired astrometric reference catalog.  allowed
+values are <tt>GSC, USNO, 2MASS, PTOLEMY, STONE</tt>.  
+
+<li> USNO_CDROM  : directory where USNO data is stored
+<li> STONE_DIR  : location of the Stone et al reference data
+<li> 2MASS_DIR  : location of the 2MASS data 
+<li> CATDIR  : location of the ptolemy data
+<li> GSCDIR  : location of the HST Guide Star Catalog
+<li> GSCFILE  : location of the GSC layout file (for GSC and ptolemy)
+
+note that 'ptolemy' refers to data using the DVO format.  2MASS data
+must be in a DVO format database.
+
+<li> RADIUS  : matching radius in arcsec to select reference stars
+<li> SIGMA_LIM  : exclude stars with formal error larger than this
+
+<li> ZERO_PT  : default zero point, nominally 25.0.  don't set this to
+a 'real' zero point.  it is used only for reference.
+
+<li> INST_MAG_MIN  : exclude stars brighter than this instrumental magnitude
+<li> INST_MAG_MAX  : exclude stars fainter than this instrumental magnitude
+<li> INST_BRIGHT  : use stars brighter than this value to measure
+systematic error limit.
+</ul>
+
