All-image limiting magnitude estimate:  14.5 (SNR )  11.4 (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.

ITERATION 01 -- talking to VizieR, this might be slow!
UCAC5 search strategy: trying local copy first
Found a local copy of UCAC5
UCAC5 local query limit 5000: matching up to 5000 detected stars, deepening the UCAC5 window to mag 15.50
Reading UCAC5 zone files...
Searching UCAC5 zones 453 to 508 (Dec 0.6 to 11.3)
Done reading UCAC5 zone files...
Matched 4887 stars with the local copy of UCAC5.
The local UCAC5 search seems to be a success
Correcting the measured astrometric positions...
Accuracy estimation diagnostic: 4866 matched stars entering correct_measured_positions(), 4866 with non-zero local correction accuracy
Estimated accuracy of the plate solution: 0.44"
