CW_OSIPL
Name
cw_osipl
Purpose
Display the various spectra generated by xdavg
Description
This program takes spectra, badflags, and profiles and displays them via a
multiple page format. Several spectra can be plotted at once by selecting
the number of columns and rows to use to display the spectra. If profiles
are provided then they are plotted alongside the spectra. A smoothing
factor can also be applied to the spectra to reduce the effects of noise.
The y-range of the plots can be specified by switching to the "fixed"
option. The automatic y-range is a min-max range. The current page can
also be printed out or all pages and the printer to which they go be
specified

cw_osipl,leader,type
Inputs
leader - the Id of the mainbase of the calling widget
type - a flag indicating whether or not the the plot is called from the top
or the bottom of the xdavg tool. Different defaults are implied by
this for the number of rows and columns as well as the size cw_osipl
Optional Input Parameters

TITLE - Optional title of widget, default = 'OSIRIS XD PLOT'
Outputs
Spectra and profiles are plotted to the screen and can be printed

Procedure
This plot widget is used by creating it as a compound widget from within the
calling program and recording its Id. Plots are then displayed by the
program by setting its value to the following data structure in a
widget_control statement:
data={
*Required information*
nspecs: The number of spectra that need to be plotted
calib: The calibration structure for the spectra
pref: The index of the spectrum that is prefered to be displayed
filenam: The filename of the spectrum, this added to the objname field
is displayed as the title of the plot
objname: The name of the object
display: The array of spectra to be plotted
badflag: The array of badflags to be plotted
pflag: Flag indicating whether profiles are to be hidden
cflag: Flag indicating whether a each order of the spetrum should be
plotted in a different color
pageflg: Flag to indicate that the plotter should only replot if the
prefered spectrum is not on the current page
*Optional information*
(required if pflag is set)
prof: The array of profiles values
index: The indices for the profile points
upbnd: The upper bound values for the sky level for the profiles
lwbnd: The lower bound values for the sky level for the profiles
relsig: The signal relative to the brightest spectrum in the set
mate: The mate used in the extraction by xdspec
airmass: The airmass for each spectrum
juldate: The Julian date of the exposure
exptime: The exposure time of the spectrum
ncoads: The # of coadds used to make the spectrum
