Note that some template spectra are defined over a limited wavelength range and may not allow calculations for all instrument configurations. The object magnitude is not taken into account for the following single line source Single line Wavelength: nm Flux: 10-16 ergs/s/cm2 (per arcsec2 for extended sources) FWHM: nm (Minimum value: 0.50) Spatial Distribution: Point Source Extended Source Sky Conditions Days From New Moon: 0 days3 days 7 days10 days 14 days Airmass: Seeing: arcsec The sky brightness is determined by the moon phase and the instrument efficiency according to this table.
