BUSCA Exposure Time Simulator                                 

(WARNING: The simulator only works for the filters u,v,b and y. For the I filter there exist only a rough estimation.)

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=  Total counts
                                             S/N=  (per pixel for an extended object)

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

Intensity Peak=  Total counts
