Build a parameterized optical model with Batoid to use for fast simulations.

I am re-titleing this rather old issue. We can use it to follow up on the discussion we began in the imSim technical meeting. With #10 will have a full...

Add satellites / other sky artifacts

Wow. Interesting. I'm not sure I understand the relationship of the blinkers to the streak. Should they be on either side of it?

Add option to write extended truth information.

In the new architecture, this feature will be tied to the collected photon lists described in #244.

Explore the possibility to store or encode the ability to recreate the PSF for each object

@jchiang87 Can we close this one too with your merger of #117?

Explore the possibility to store or encode the ability to recreate the PSF for each object

OK I will leave this open.

Explore the possibility to store or encode the ability to recreate the PSF for each object

@jchiang87 I think you were recreating PSFs for some objects for some of the validation examples. Is that right? Or was it for something else? If yes, does that mean...

Explore the possibility to store or encode the ability to recreate the PSF for each object

Thanks. For this code, we are only talking about the atmospheric PSF correct? Do we have the random #s stored that we would need if we also wanted to include...

Explore the possibility to store or encode the ability to recreate the PSF for each object

> A single rng is used for both. OK great. I wonder if we could put a generalized version of your snippet above (with input at a particular position) somewhere...

Explore the possibility to store or encode the ability to recreate the PSF for each object

I think there are several interesting use cases if we could know the PSF model before the sensor for a given object. This way we could do things like compare...

Consider a consistent use of units throughout the program.

Semi related: How are all defaults recorded? Externally in documentation but hardcoded? Or also though this mechanism?
