Otherwise, MaNGA piggybacking won't get good data. If there are no eBOSS = carts available, you can use a MaNGA cart to do the BOSS calibration.=20 best, -renbin On Dec 4, 2014, at 6:58 AM, pgaulme@apo.nmsu.edu wrote: > This night is APOGEE only, so I did limited > BOSS calibrations of bias and 20 sec dark.=20 > Used isBoss Bypass to do BOSS calibrations=20 > using APOGEE cartridge.=20 > All looked ok.=20 > Median spectrographs temperatures: > Tsp1=3D 10.9, Tsp2=3D 10.3; =20 > Outside air temperature=3D 11.7; =20 -- Renbin Yan Assistant Professor Department of Physics and Astronomy 177 Chemistry-Physics Building University of Kentucky Lexington, KY, 40506-0055 (1) 859-257-0795
