In photometry mode the telescope follows a pre-determined Lissajous pattern to map a 30″ diameter region of sky. All overheads are included in this mapping calculation.
How much time do I need to measure the flux of a 5 mJy known point source with a S/N of 10?
Source flux = 5 mJy
S/N = 10
Required Integration Time = 1319 seconds
Positional Uncertainty = 0.5 arcseconds
