OBSERVER'S REPORT TNG, 2001, JULY 12 (AXIS Project, ITP time) Observers: A.Caccianiga, J. Tedds Instrument: TNG+DOLORES Grism : LR-B, LR-R slit : 1.5" frame : trimmed in Y for the spectra (500->1500) Weather conditions: good Seeing : from 1.5" to 1.7" Technical problems: @ 00am -Software problems. Lost about 30min. As a consequence of this problem, the FITS files are collected in 2 different sequence names: EQLFXXXX (observations before midnight) and EQLGXXXX (observations after midnight). @ 03am -The rotator/adapter at the Nasmyth B focus stopped working. Lost the remaining part of the night.
