All-image limiting magnitude estimate:  14.1 (SNR )  11.1 (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.

All-image limiting magnitude estimate:  14.3 (SNR )  13.6 (80% of stars)  with default.sex.telephoto_lens_vSTL
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.
