If there isn't another set with more suitable illumination, I'm hoping we can manually scale them to match the actual throughput from the sky (via a twilight exposure, maybe?).</p> <p>We have to sort out the fibre throughputs.  Twilight sky is one option (with field rotation!) but it's a bit tricky to get.  Another option is to use the bright sky lines (e.g. 5577 in the blue, and reasonably-isolated sets of Meinel lines in the red).  They should be uniform across the field of view to a percent or two, and we can beat that down as sqrt(N).  It'd be good to confirm that both approaches give the same result.</p> <p>Thanks. </p> <p>I'll close this ticket based on the CALIB created, and file a new ticket to improve the fiber throughputs.</p> <p>Latest calib update also copied to Tiger: <tt>/projects/HSC/PFS/Subaru/CALIB</tt> (no symlink).</p> Relates PIPE2D-1133 Development Rank 0|zzsvrx:c Reviewers price Sprint PreEngRun09Dec
