Run some Mdwarfs #59

Closed bjfultn closed 7 years ago

bjfultn commented 7 years ago

Run a small sample of Mdwarfs from both Keck and APF with high SNR observations.

bjfultn commented 7 years ago

I ran GL699 (Barnard's Star) for both APF and Keck.

Keck velocities vs. BC (CPS RMS = 2.5 m/s): iGrand_GL699_bcbyiter.pdf

Send Jay Keck GL699 spectra

bjfultn commented 7 years ago

Jay says that template convergence is not working well for Mdwarfs.

bjfultn commented 7 years ago

APF RMS is a factor of ~2 better than before with the more finely sampled template. Still shows some systematics with BC, but BC phase coverage is poor.

Keck is looking much better and approaching the 2.5 m/s RMS of the CPS code.

Order 2 is performing very poorly, but I suspect it is not affecting the final results too much because of the weighting scheme. iGrand_GL699_bcbyord.pdf
