Re: R > 72000 ?! [1 Attachment] Ken, I didn’t reveal the full story ... because my main objective is achieving high SNR (400) and not a high R I’m using a 35u slit and 2x2 binning, hence

Re: R > 72000 ?! Bernard, The SimSpec V4 for a 20 micron slit gap and an ATik314L camera gives: for 1 x 1 binning, R=9010 for 2 x 2 binning, R=8452. Any difference(s) is not

Re: R > 72000 ?! [4 Attachments] Hi Alfonso, Thanks for the unsaturated argon spectra which does allow a good FWHM, which I measure as 0.105A at the 5062A argon line, so R=48,000. Confirmation

Re: R > 72000 ?! Answering the requeriment of Benji, I join a fit file of my better focus of the calibrate lamp; a pgn file with the R mesured with BASS, and a fit 1D file.

Re: R > 72000 ?? Hi Alfonso, I fully agree with Benji’s suggestion. Also, something is very doubtful about your argon calibration if, as you report, the SNR=1. Cheers,
