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 

Magnitudes are given per square arcsec for extended sources.

Results

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

 Exposure Time settings:
                  NDIT:  
                  NINT: 

On submission the model can generate the following graphs:
