L=A[sig]T4
f=L/A=[sig]T4
Where does time come into these equations?
If one telescope of a known diameter can reach a certain magnitude, it is easy to find what magnitude a different telescope of known magnitude can reach. But if a telescope integrating over 10s can reach a certain magnitude, how can we determine what magnitude the same telescope will reach integrating over 1hr?
Also, what does it mean for something to have a spectral resolution of 5?
