Finding Nearby Standard Stars for Michelle Calibration

Enter a target position below (format as in the OT, say 16:44:29.470 and 23:47:58.20 for RA and Dec respectively). Also enter the length of the observation. The task will return the names of the 10 closest stellar standards one might use for photometric or low resolution spectroscopic calibration for three positions: (1) the target position; (2) same declination, right ascension less by half the entered exposure time; and (3) same declination, right ascension plus half the entered exposure time.

For example for a 2 hour exposure the task will look for standards at RA 1 hour less and 1 hour more than the target position as well as using the target position. Three sets of potential standards are returned.
