 Template Spectra:   Redshift Z = 

 Single line
	Wavelength:      nm
	Flux:            10-16 ergs/s/cm2 (per arcsec2 for extended sources)
	FWHM:            nm (Minimum value: 0.50)

 Object Magnitude:   Band:  Vega AB

Spatial Distribution:

  Point Source
		  Extended Source

 Extended Source: Integral Photometry

	Aperture Radius  arcsec

Indicate the desired aperture magnitude in the broad band associated filter, and the aperture radius


Sky Conditions

Days From New Moon: Airmass: Seeing: arcsec

The sky brightness is determined by the moon phase according to this table.
