You cannot rely on UT and draw conclusions on this basis (including regarding the correctness of declination) if you read UT when measuring the Sun, because there are 2 precisely established facts:
1. The declination of the Sun SH5 does not correspond to the actual declination of the Sun (you can check on your mod with the checkpoints on March 20, June 22, September 23, December 22).
2. The time correction is performed on the basis of the actual declination of the Sun (see file Sun.txt), and therefore gives a deliberately incorrect result.
The only exceptions are measurements taken around March 20 and September 23.
