/**
Reads a plot control file that contains instructions on what to plot
and how to plot it.
There are a few plotting module that understand different commands
and plot different kinds of things.
Common plotting:
plot_color (<r> <g> <b> <a> or color name)
plot_lw <linewidth>
plot_bgcolor (<r> <g> <b> <a> or color name)
plot_bglw <linewidth>
plot_marker <marker-shape>
plot_markersize <radius>
plot_wcs <filename>
plot_wcs_setsize
plot_wcs_box <ra> <dec> <width> -- center on RA,Dec with width in deg.
Fill with a color:
fill
Image:
image_file <fn>
image_format <format>
image_ext <extension> -- FITS extension
image_wcs <fn> -- project the image through its WCS, then back through the plot_wcs.
image_setsize -- set plot size to image size.
image_low -- FITS pixel value that will be black.
image_high -- FITS pixel value that will be black.
image_null -- FITS pixel value that will be transparent.
image
Xy:
Note, xylists are assumed to contain FITS-indexed pixels: the center of
the "lower-left" pixel is at coordinate (1,1).
xy_file <xylist>
xy_wcs <wcs-file>
xy_ext <fits-extension>
xy_xcol <column-name>
xy_ycol <column-name>
xy_xoff <pixel-offset> -- default 1, for FITS pixels.
xy_yoff <pixel-offset>
xy_firstobj <obj-num>
xy_nobjs <n>
xy_scale <factor>
xy_vals <x> <y> -- coordinates to plot
xy
RA,Dec lists:
radec_file <filename (FITS binary table)>
radec_ext <FITS extension, default 1>
radec_racol <FITS column name, default "RA">
radec_deccol <FITS column name, default "DEC">
radec_firstobj <int, default 0>
radec_nobjs <int, default no limit>
radec_vals <ra> <dec> -- coordinates to plot
Annotations:
annotations_bgcolor
annotations_fontsize
annotations_font
annotations_target <ra> <dec> <label>
annotations_targetname <label> -- eg "M 8", "NGC 427"
annotations_no_ngc -- don't plot NGC/IC galaxies
annotations_no_bright -- don't plot named stars
annotations_ngc_size <fraction> -- default 0.02, min size to annotate.
annotations
Image outlines:
outline_wcs <fn>
outline_step <pix> -- step size for walking the image boundary, default 10
outline
RA,Dec grid:
grid_rastep <deg>
grid_decstep <deg>
grid_ralabelstep <deg>
grid_declabelstep <deg>
grid_step <deg> -- sets all the above at once.
grid
Astrometry.net index files:
index_file <filename>
index_draw_stars <0/1> -- draw stars?
index_draw_quads <0/1> -- draw quads?
index
Healpix boundaries:
healpix_nside <int>
healpix
