MCCLASS / PLOT

Purpose:

Plot the measured SED and the template for an object from a flux table style catalogue. Such plots allow to spot inconsistencies between measured data and best-fitting templates found in the classification.

Syntax:		MCCLASS/PLOT  [tab] [i] [templ] [class] [z] [ax] [tsize]

	   	   tab        = Name of input object catalogue
				(default: flux_table)
		   i	      = Number of object in the table
				(default: 1)
		   templ      = plot template or not?
				(default: template)
		   class      = desired template class name
				(default: :mc_class, i.e. take from column!)
		   z          = desired template redshift value 
				(default: :mc_z, i.e. take from column!)
		   ax         = axis definition for plot panel, reset by
				commands mc_plot_table1/table4/table6.prg 
				(default: -160,-60,18,50)
		   tsize      = legend text size, reset by
				commands mc_plot_table1/table4/table6.prg 
				(default: 1.5)


Examples:	MCCLASS/PLOT  cat_A901_J2003c 11756 
		MCCLASS/PLOT  cat_A901_J2003c 11756  notemp
		MCCLASS/PLOT  cat_A901_J2003c 11756  ?  star
		MCCLASS/PLOT  cat_A901_J2003c 11756  ?  qso  5.0

Remarks:

This command looks for the spectral libraries mc_plot_*_spec.tbl in the MID_WORK directory. These are required if template overplotting is desired (get them from $MCC). They should be destroyable copies of the template libraries used for generating colour libraries, because they will suffer from write-access by the plot program and can not be turned into colour libraries any more after this happens.
The command creates a plot in the MIDAS graphics window and a postscript file for an A4 size paper print. A number of further parameters can be changed, if the user creates a local copy of the MCC:mc_plot_f04.prg file which then provides write access. The setup variables in the header of the prg available for user manipulation include choices of

the spectral template libraries for overplotting
linear or logarithmic wavelength axis
linear (flux) or logarithmic (Asinh magnitude, needs to exist before plotting) vertical axis
manual or automatic (driven by filters) plotted wavelength range
manual or automatic (driven by fluxes) plotted flux range
manual or automatic (driven by flux errors) weighting for template normalization
paper or ppt (Powerpoint) style in colours, fonts and label sizes
values for xmin, xmax, xstep, ymin, ymax in manual range settings
up to three flux+error columns chosen for the template normalization
a magnitude column and label to be reported in the text labels accompanying the plot

The command @@ MCC:mc_plot_table1 as well as @@ MCC:mc_plot_table4 and @@ MCC:mc_plot_table6 loop over an entire table and plot all contained objects sequentially. 1/4/6 refers to the number of objects per A4-size page. At six objects per page, the textual data about the objects are dropped to save space for the plot panels.
Sometimes the colour indices in the table are not directly calculated from the flux or magnitude data, but involve corrections for interstellar reddening or for residual calibration errors. These corrections should be specified by the descriptor "cal_corr". It will also be used to correct the flux or magnitude data in the plot, in order to resemble the colour indices for comparison with the templates.
