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 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.

The local UCAC5 search seems to be a success Accuracy estimation diagnostic: 4891 matched stars entering correct_measured_positions(), 10807 with non-zero local correction accuracy Estimated accuracy of the plate solution: 0.39" Accuracy estimation diagnostic: 4891 matched stars entering correct_measured_positions(), 10807 with non-zero local correction accuracy Estimated accuracy of the plate solution: 0.39" Excluding outliers - 4891 stars left (next iteration limit 5377) Stop iterations.
