To get the coordinates of stars near a given targets use mboxofstars. The Yale bright star catalog and FK5 catalogs are available thru the bright command. Many photometric standard star coordinates and magnitudes are available thru the landolt command. FLOW Incoming request files arrive by e-mail to the telescope control directory. The current sky conditions are determined by the dostandard program which does observes equatorial standards and compares the photometry to the catalog value and an empirically determined zero point.
Any excess is attibuted to extinction.
