Astronomy and astrophysics core library
A star delta has been computed for 62,252 of 63,108 tracked repositories in this period, and only those can be ranked in it.
A repository missing here has not been measured far enough back yet. That does not mean it did not move.
Star counts measured between 02:22 and 10:01 (BKK).
