Quote from: alancalverd on Today at 09:21:10Detection efficiency isn't relevant - you have to integrate over a reasonable period to determine intensity.
If we initially detect intensity I1 at pixel A and 0 at A + 1, then subsequently detect I A < I1 and I A+1 > 0, we can infer.......
..... that the pixels just don't click with 100% effectiveness? that the air changed its density locally? or maybe that the source image was rotating.
Air density and turbulence may have been problems for neanderthal astronomers, but any respectable Waitrose customer buys his data from space telescopes nowadays.
