I will now break down each of these seperately.
The first part lets the user set which charts to display. Set to 'y' to display a chart when running IGRINS Observability, set to 'n' to not display the chart.
y #Show telescope Hour Angle observing limits
This displays a chart showing the limits of where the 2.7 m telescope can slew in Hour Angle and Declination. The observing limit chart is a recreation of this chart, with the declination of the target painted on as red circle.
y #Show altitude vs. Local Siderial Time plot with telescope observing limits
This is an altitude chart showing the altitude of the target above the horizon vs. local sidereal time as the blue line, . The two red vertical lines show the observing limits of the telescope. These charts are designed to mimic the Altitude charts created by
y #Show finder chart for IGRINS Slit View Camera FOV
And here we get to the meat of the code, making a finder chart! The green outline is the Slit View Camera FOV. The box in the center is the slit. The Blue compass shows the directions of North and East. I will go into much more detail on how this all works in the rest of this manual
