Note (1): Check star(s) were used for almost all runs.
In some cases, the fields were sparse and there were no suitable check
stars. In other cases, the C-K (differential comparison-check
magnitude) plots revealed some abnormal slope, thereby compromising
accuracy. In these cases, the estimated error was adjusted upward.
