How to generate a source with only main sequence stars? about artpop HOT 2 CLOSED

Hey @PaulLiu666 – I think the simplest approach would be to build the source object from the ground up:

• generate a stellar population and use the MS-star boolean mask to get the stellar mags (like you did to make the figure)
• generate xy positions for each star using sersic_xy
• Use the xy positions and mags to initialize a Source object.

If your end goal is to simply create an RGB image of the source, the observe method of Imager objects have an optional mask argument for selecting the stars you want to inject.

This is how we made the figure below in the ArtPop paper:

The script for making this figure is here.
