These measurements can still be=20 useful for the future. Also, we will need the lossy fiber data on r2. So = I recommend we still try to=20 get lossy fiber data on SP2.=20 best, -renbin On Aug 20, 2016, at 6:02 AM, dmbiz@apo.nmsu.edu wrote: >=20 > APACHE POINT OBSERVATORY SDSS 2.5M >=20 > OBSERVING LOG > Friday August 19, 2016 >=20 > (SJD 57620) >=20 > ---- Observing Team ---- >=20 > Dmitry Bizyaev >=20 > Kaike Pan (first half night) >=20 >=20 >=20 > ---- Observing Summary ---- >=20 >=20 > Given Renbin's results on the sp2 tilts, we did not do any=20 > tests with spectrographs tonight.=20 >=20 > Unfortunately, the lossy fiber lamp was set for sp2 > for cart 8, so we did not do it either.=20 >=20 > Regular flats and an arc were taken.=20 > We also queued 21 15-min darks for tonight. =20 >=20 >=20 > ---- Observing Plan ---- >=20 > More tests.=20 >=20 >=20 > ---- Observing Log ---- >=20 > Checked software, actors, guider, plates, platedb. >=20 > Collimated spectrograph with cart 11 and took=20 > 3 flats and an arc.=20 >=20 > Tried to mount cart 8, but then found that =20 > lossy fiber LED was placed on the sp2 side > of the cartridge.
