Inputs

stand - String array of standard names. (See coord.)
fil - String array of filter names for observations.
jd - Double precision array of the JD of observations.
time - Floating point array of the UT time of observations.
am - Floating point array of the airmass of observations.
serial - Serial number of observation.
inst - Instrumental magnitude
instsig - Uncertainty of the instrumental magnitude
color - Standard system color for object.
colorsig - Uncertainty on the standard color
doobj - Name of object to reduce.
doser - Serial number of object to reduce.
dofil - Name of filter to reduce.
tran - Transformation coefficients (vector)
tran(0) = principal extinction coefficient
tran(1) = second order extinction coefficient
tran(2) = color term
tran(3) = zero-point
tran(4) = time-dependent extinction term
tran[5] = (f) airmass squared term
tran[6] = (g) color squared term
transig - Uncertainty on the transformation coefficients (vector).
jdref - Time reference point for extinction
refcolor - Color reference for the color term transformation.
This term is normally C * (B-V) or some other standard
color. This formulation uses
C * ( (B-V) - REFCOLOR ) for the term instead.
refam - Air mass reference for the transformation.

Optional Input Parameters

Keyword Input Parameters

APPEND - Flag, if true, data will be appended to FILE
BADFLAGS - Array of flags that mark data bad (if true).
COLORNAME- Name of color used for color, colorsig (such as 'B-V').
DATABASE - Name of MYSQL database to save reduced observations.
The default is 'phot'.
DB - Flag, if set, reduced observations will be saved to database.
DVERBOSE- Code for dbphot and other routines for db transaction verbosity.
FILTNAME - String name for selected filter, default for 2=V and 3=R.
FILE - If supplied, the reduced lightcurve will be saved to this file.
NOEDIT - Flag, if set inhibits final interactive editing of fitted points.
This keyword has no effect and is not necessary if the current
plotting device is 'PS'.
NOPLOT - Flag, if set, suppresses a plot of the final lightcurve.
NOSAVE - Flag, if true, will inhibit modification of files or databases.
PLOTWIN - Plot window to use for output plots (default = current window)
REFID - String uniquely identifying observing run. This is used in
updating the data table in the phot
database. It must be specified if DB is used.
TABLE - Name of table in MYSQL database to save reduced observations.
The default is 'data'.

Keyword Output Parameters

BADFLAGS - Array of flags that mark data bad (if true).
NOBS - Number of points reduced.

Outputs

jdobs - JD of observation for each point.
tobs - UT Time of observation for each point.
std - Standard magnitude.
stdsig - Uncertainty of the standard magnitude.

Common Blocks

Side Effects

Writes file of lightcurve data if FILE specified.
Updates MYSQL database with lightcurve data if DB set.

Procedure

Modification History

Written: 1992 Mar 31, Marc W. Buie, Lowell Observatory.
96/10/16 - MWB - added NOPLOT keyword
96/01/24, MWB, added BADFLAGS
2006/08/10, Peter L. Collins, Lowell Observatory, add data base
output for reduced obs, dbphot, slight header and print cleanup.
2006/09/26, PLC, add INSTRUMENT keyword to pass through to dbphot.
2006/10/16, PLC, add NOSAVE keyword.
2006/12/07, PLC, replace instrument and rundate keywords by REFID and
change calls to dbphot.
2006/12/14, MWB, added PLOTWIN keyword.
2006/12/28, PLC, added DVERBOSE keyword.
2007/02/15, PLC, added NOBS and COLORNAME keywords. Include color in
photometry database. Somewhat better editing options for
badflags with markdata.
2014/03/06, MWB, added refcolor and refam (this changes the calling sequence)
added support for extra transformation terms
non-DB functions are deprecated
