Maximum allowed flux for a point source in erg s-1 cm-2 е-1. Maximum peak allowed flux for an extended source in erg s-1 cm-2 е-1 arcsec-2. V magnitude limit for unreddened single stars. O5 V through F8 V are based on Kurucz models. The magnitudes listed for G2 V are for the Solar template in the STIS ETC. The magnitudes listed for G8 V are from IUE data for the star Tau Ceti. The magnitudes listed for K2 V are from IUE data for the star Epsilon Eri. The magnitudes listed for KM III are from IUE data for 9 stars of these types. Maximum integrated V magnitude for stars in the field assuming all are of O5 V spectral type. Maximum allowed flux for an extended source which covers the full detector in erg s-1 cm-2 е-1 arcsec-2
