All-image limiting magnitude estimate:  14.7 (SNR )  11.6 (80% of stars)  with default.sex.telephoto_lens_onlybrightstars_v1
The first estimate is the magnitude of a star detected with a signal-to-noise ratio of  following Karpov (2025, Acta Polytechnica, 65, 50). 
This value should be representative of the faintest stars clearly visible in the image. 
The brighter of the limiting magnitude estimates for the two second-epoch images is reported here.
The second estimate is the 80th percentile of the magnitude distribution of stars detected on all four images.
This value is representative of the faintest object that may enter the candidate transients list.
The hard cut-off for the candidate transients is 15.5 mag.

Found a local copy of UCAC5

Matched 4590 stars with the local copy of UCAC5.
The local UCAC5 search seems to be a success
SIP_REFIT: re-match found 4590 pairs (4795 from the initial matching)

SIP_REFIT: the refit on the re-matched pairs is worse than the solution it would replace (worst-region 0.452 vs 0.450 arcsec) - keeping the current solution
SIP_REFIT: the second refit on the re-matched pairs was not applied - keeping the first refit solution
