IMAGING Exposure Time Simulator                                 Version 1.0.0


Source Info

Object:                   Object Magnitude=  mag or mag/arcsec2

Atmosphere

Airmass=                    Seeing=   arcsec

Instrument Setup

Optics:  Filter:  

Observation Setup

Integration Time=  sec      Number of Frames=  

The total Exposure Time is the product of the Integration Time and the Number of Frames.


Calculations and Outputs


      Object Signal=  counts/s
                                            S/N=  (per pixel for an extended source)

For a point source object the simulator also calculates the signal at the intensity peak.

Intensity Peak=  counts/s
