tassiv_reduce.cfg
	Configuration file used by scripts.  Set TASSIV_CFG env variable for
	location.

dbCreate.pl
	Runs the appropriate scripts to create/load the dB.  Hard coded
	location to Tycho2 dataset.  
dbSchema.sql
	dB definition.
dbLoadTycho2.pl
	Loads the Tycho2 database, with some light selection criteria
dbSeedubvri.pl
	Takes what's in the tycho2 table and loads reference_ubvri (per Arne's
	conversion equations.  Probably need a location reference table also.
dbIndexes.sql
	All the index the dB uses.
dbTriggers.sql
	The trigger creation
dbTypes.sql
	An abortive attempt at RA type.  Needs to become Ra/Dec type.

Makefile
	Used to build the triggers and types.  A hack of a make file
tassiv_triggers.c
	The trigger which provides the link between catalog the catalog
	table and the obs_? tables.
dbTypes.c
	Abortive attempt at RA type.

importSList.pl
	Given a directory, imports pairs of star lists at a time.  Also clips
	stars that are not in both bands.
mergeStars.pl
	Searches dB for stars that do not have an associated entry in
	catalog table.  When 10 entries are found, a new entry is created.
	Also updates existing stars.  Will use star id's from reference_ubvri
	table when a star matches one from there.
color.pl
	Calculates the color terms for a group (night) of stars, along with
	zero points per frame.  Uses an iterative algorithm, which is slow,
	but easy and it works :-)  Sets the mag column of the obs_? tables,
	using the imag column.  Equation is:
	mag = obs_i.imag + zp.zero_i + cg.color_i * (v.imag - obs_i.imag)
	for the obs_i table.
welch.pl
	Calculates the Welch-Stetson statistic on updated and new entries.
	mergeStars.pl will set the updated = FALSE when it adds entries to
	a star.
