Physical star spot modeling with limb darkening

See original GitHub issue

Hello. Starry is very useful and convenient for me. Thank you.

Now, I am trying to model star spots. For physical modeling, I would like to compare starry’s gaussian amplitude(add_gaussian()) and star spot temperature. I think we can compute it by comparing intensity from black body and a value of star spot model. (For example, if the star spot locates at x=0, y=0, we can get the amplitude value of the star spot by using map(x=0, y=0) in https://rodluger.github.io/starry/v0.3.0/tutorials/basics1.html#Using-starry)

However, If the star have some star spots, the amplitude was tempted by normalization. How can I get this value? I came up with two ideas.

  1. Make a new map(lat, lon) option
  2. Make a new option to prohibit a normalization. I prefer No.2, because this make us easy to set up the desired star spots.

Do you have any ideas to solve this?

Thank you.

Hi @rodluger, Thank you. Now, I understood the specification of the add_spot(intensity= ).

Added option is very nice! I tried it and confirmed my issue was solved. Thank you for your kindness and quick responses.
