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.

Please investigate this! ************************************************************** This error might be a bug, but it is far more likely that it is caused by inappropriate input data. A few simple things to check in the diagnostic messages printed above (or the vast*.log files): * How many of the input images are matched? * Does the number of detected stars on each image look reasonable? * Do images have a sufficient overlap of at least about 20 percent? You may run ./sextract_single_image /path/to/my/image/file.fit to see how well VaST detects stars with the current SExtractor settings (star detection settings can be changed in the default.sex configuration file, see various examples in the VaST directory). If you cannot identify the problem, please e-mail Kirill Sokolovsky Please try to describe the problem in details and, if possible, attach vast_summary.log file and a few example images. If the images are too big to be sent by e-mail, please upload them through a web-form http://scan.sai.msu.ru/upload/ ************************************************************** Low percentage of
