... First, there is a set of residual plots against airmass for each night. ... If you reply ``YES'', it will show you some plots intended to help you distinguish between time-dependent extinction and time-dependent zero-point drift. ... Figure: Sample drift plot . The principle behind these plots is that time-dependent extinction produces errors (and hence, we hope, residuals) that are proportional to airmass; but instrumental drift produces residuals uncorrelated with airmass. ...
