f2fig

Description

f2fig reads data in GLESP FITS format and outputs the figure file in GIF (Graphics Interchange Format). f2fig allows to put markers on the figure at given positions.

Examples

1. Plotting the figure
   • f2fig map.fits -o map.gif
     reads the map from ' map.fits' and outputs the map to ' map.gif' with lowest/highest temperature values as the colorbar limit. The default colorbar hue is Rainbow.

   • f2fig map.fits -o map.gif -Cs -0.2,0.2 -c 3
     reads the map from ' map.fits'. Set the colorbar hue as Red/White linear and force its limits on [-0.2,0.2]. The output is in ' map.gif'.

   • f2fig map.fits -o map.gif -C -0.2,0.2
     reads the map from ' map.fits'. The output is in ' map.gif' with colorbar limits set at [-0.2,0.2].

2. Plotting the figure and placing one marker
   • f2fig map.fits -o map.gif -mr "1.571 1.450 2 15 90"
     reads the map from ' map.fits'. A red (90) plus (2) marker, sized 15 pixels is placed at ($\theta$, $\phi$)=(1.571, 1.450) of spherical coordinate. The output is in ' map.gif' with colorbar limits set by the lowest and highest temperature values.

   • f2fig map.fits -o map.gif -C -10,10 -mr 50d,20d,5,10,1 -cr
     reads the map from ' map.fits'. A white filled diamond marker, sized 10 pixels is placed at $(b,l)=(50,20)$ degrees. The output is recorded in file ' map.gif' with colorbar limits set at [-10,10].

   • f2fig map.fits -o map.gif -Cs -0.2,0.2 -mr 06:45:00, -16:43:00, o,30,0 -feq
     reads the map from ' map.fits'. A black circle marker, sized 30 pixels is placed at (R.A., Dec.)=(6h 45m, -16degs 43m). The output is in ' map.gif' with colorbar limits forced to be [-0.2,0.2].
3. Plotting the figure and placing multiple markers
   • f2fig map.fits -o map.gif -fs pointsource.txt -cr
     reads the map from ' map.fits'. A list of extragalactic point sources filed in ' pointsource.txt' is read in with Galactic coordinates. The marker shape, size and color are denoted in the file. The output is in ' map.gif' with the lowest and highest temperature values as colorbar limits.
