Don Cross	9975edc81b	Updated star database to HYG v 3.6.1.	2023-09-21 15:41:03 -04:00
Don Cross	f4405e390c	Updated star database to HYG v 3.5.1. ... This change affects internal unit testing only. It does not affect developers who use Astronomy Engine. Upgraded the HYG database used for verification of constellation calculations to v 3.5.1. See conversation at: https://github.com/astronexus/HYG-Database/issues/21	2023-09-19 15:08:49 -04:00
Don Cross	5eca7d7760	CodeQL tweaks and fixes. ... Updated CodeQL config to ignore source templates, because they are not syntactically valid source code. Ignore other stuff that is irrelevant to published code quality. Made various fixes based on helpful CodeQL analysis.	2022-11-07 15:31:05 -05:00
Don Cross	a9b9652c5d	Added sample Python program stars_near_moon.py. ... Tonight as I was walking outside, I saw a fairly bright star about half a degree away from the edge of the Moon. I wondered what it was, so I decided to write a quick program to find out. This Python demo program scans the HYG Database (https://github.com/astronexus/HYG-Database) to find which bright stars are within a small angular distance of the Moon, as seen at a given time, latitude, and longitude. It turns out the star I saw was Nunki (Sigma Sagittarii). It was handy to do vector subtraction to implement this program, and it was trivial to do in the Python code's Vector class, so I went ahead and added that.	2021-11-08 21:44:36 -05:00
