Input Flux Distribution

 

 Continuum (Flat Spectra)
 Blackbody: T =		 Kelvin
 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 (Vega system):   Band: 

Spatial Distribution:

 Point Source
		 Extended Source

 	Surface Brightness     Semi-Major Axis  arcsec   

 For De Vaucouleurs and Exponential profiles, the Projected Semi-Major Axis is intended
 as the Effective Radius along the slit.

Sky Conditions

Days From New Moon: Airmass: Seeing: arcsec

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