Input Flux Distribution

 Uniform (constant with wavelength)
 Blackbody: T =		 Kelvin
 Template Spectra:	  Redshift Z = 

 Object Magnitude:  Band:   Vega AB

Magnitudes are given per square arcsec for extended sources. 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 option 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
