DESCRIPTION

CALFLUX returns the flux (in Jy) of a calibrator source at a given frequency (in GHz). The source resides in a calibration file that is formatted such that each record is composed of white space separated fields ordered Source, Day (yymmmdd.d), Freq (GHz), Flux (Jy), and rms (Jy). Lines beginning with a "!" are excluded. Warnings are returned if there is no match of the source in the calibrator file, if there is no matching entry at the desired frequency, or the observation date is greater than 4 years. The Day field, presently, is formatted as yymmmdd.d where yy is the year field 19yy, mmm is the three character string of the month, and dd.d is the decimal value of days. None of the inputs are required, but they provide a means of bracketing the desired source(s).  

PARAMETERS

in
Name of the calibration data file (Default is the file cals.fluxes in the directory MIRCAT).
source
Name of the calibration source to list (default is all sources). The source name is minimum match format.
freq
Frequency that the source was observed at in GHz (default is 0.0, which implies all frequencies are valid matches).
delfreq
A full width in GHz (default is 5.0) in which to accept deviations from the value of ``freq'' as a match. If ``freq'' is not given or is set to the default value, this input is ignored.
date
The cutoff date before or after which no observations are listed (default is date=1.0, which implies all dates are valid matches). If ``date=0'', then only the most recent data is listed. If ``date>0,'' then all data more recent than ``date'' are listed; ``date<0,'' then all data prior to ``abs(date)'' are presented. The format for ``date'' is the same as the DATE field in the flux calibration file: either ``yymmmdd.d'' or ``yymmmdd:hh:mm:ss.s'' with no internal spaces (the first 7 characters are required).
deldate
A full width in Julian days (default is 0.0) in which to accept deviations from the value of ``date'' as a match. If ``date'' is not given or it is set to the default value, then this input is ignored.
flux
The lower limit flux value to consider as a match (default is all matching fluxes).
device
PGPLOT device to plot flux versus time. Default is no plot.
xrange
Plot range in the x-direction. 2 values in format year.fraction Default is to self scale.
yrange
Plot range in the y-direction. 2 values. Default is to self scale.
