PLOTSPEC

Name

plotspec

Purpose

Plot OSIRIS XD spectral data with wavelength scale.

Description

Calling Sequence

plotspec,calib,spec,YRANGE=yrange,TITLE=title,SMOOTH=smo_fac

Inputs

calib- Anonymous structure containing all pertinent calibration
information. This structure is usually loaded beforehand using
the routine, "ldcalir"
spec - 1-D spectrum vector.

Optional Input Parameters

Keyword Input Parameters

BADFLAGS = Flag array, same length as spec. If set, the data point is bad
and should not be plotted. Default is to plot all.
COLOR = color index for data plot, does not affect the axes and labels.
If a scalar is provided, the same color is applied to all orders.
A vector implies that the colors in the vector should be applied
to each order. If the color "array" has fewer elements than
there are orders, then the last color is replicated to all the
remaining orders.
OPLOT = flag, if set, plot is overplotted, axes are not redrawn.
XRANGE = (same as PLOT control, default is min to max), ignored if OPLOT set
YRANGE = (same as PLOT control, default is min to max), ignored if OPLOT set
TITLE = (same as PLOT control, default is blank)
SMOOTH = smoothing factor for data, default is no smoothing. Uses
the smooth() function on each order individually.
LOWESS = order of polynomial for lowess smoothing. If lowess=0 (default)
then the smoothing is done using the IDL built-in smooth function.
for values of lowess > 0, lowess smoothing is done with this order
smoothing polynomial function.
NORDER = Order of spectrum to plot (default=plot all orders). This can be
a vector that lists more than one order to plot.
NOWAVENUM = Flag, if set suppresses the wavenumber axis labeling on the
top of the plot.
Accepts all other PLOT and OPLOT keywords.

Outputs

plot to current output device with wavelength scale. Each order is
plotted a disconnected line from the other orders.
