Input Flux Distribution

 Uniform (constant with wavelength)
 Blackbody: Temperature:  Kelvin

Object Magnitude: 

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

Results

The total exposure time, for non-chopping mode, is the product of DIT (Detector Integration Time) and NDIT (number of DITs). This exposure time does not take into account instrument and telecope overheads.

On submission the model can generate the following graphs:
