CAFOS IMAGING Exposure Time Simulator

Based on Zero Points

Source Info

Object:                   Object Magnitude=  mag or mag/arcsec2


Airmass=                    Seeing=   arcsec

Instrument Setup


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      Counts/s
S/N=(*)                 (per pixel for an extended source)
* S/N in e-, SITe-1d gain 1.45e-/ADU

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

Intensity Peak=  Counts     counts/s
