PhoSim Tutorial 20: How to Experiment with Different Aperture Sizes

There are a series of generic telescopes implemented in PhoSim with different aperture sizes. This will allow you to quickly experiment with different aperture sizes and compare the images. An example of this is to use the following command.

phosim examples/large_catalog -i generic_1cm -c examples/quickbackground --ds9

This results in the following image (using invert color map in ds9):

We repeat this simulation with different aperture sizes. For a 2 cm aperture we use this command and obtain more photons.

phosim examples/large_catalog -i generic_2cm -c examples/quickbackground --ds9

For a 4 cm aperture:

phosim examples/large_catalog -i generic_4cm -c examples/quickbackground --ds9

For a 10 cm aperture:

phosim examples/large_catalog -i generic_10cm -c examples/quickbackground --ds9

For a 20 cm aperture:

phosim examples/large_catalog -i generic_20cm -c examples/quickbackground --ds9

For a 40 cm aperture:

phosim examples/large_catalog -i generic_40cm -c examples/quickbackground --ds9

For a 1m aperture:

phosim examples/large_catalog -i generic_1m -c examples/quickbackground --ds9

For a 2m aperture:

phosim examples/large_catalog -i generic_2m -c examples/quickbackground --ds9

For a 4m aperture:

phosim examples/large_catalog -i generic_4m -c examples/quickbackground --ds9

For a 10m aperture:

phosim examples/large_catalog -i generic_10m -c examples/quickbackground --ds9
