Following this question:

Calculate lines of equal solar altitude

I would like to have the possibility of displaying the lines of equal solar altitude on the map as per the image below:

enter image description here

including also the values below the horizon.

Is there any software or (for example) Pythin library, which could do something like this?

  • $\begingroup$ One way would be to compute the Geographic Position of a body, then plot a circle of equal altitude around it for each ring you want. $\endgroup$ Mar 24 at 13:39
