2006 VTT OPTICON OBSERVING CAMPAIGN - NOTES: REMARKS: Thu Nov 28 : clear sky but several cirruses SP : 5434 A: 0 degrees (AO, some images only) run: 250 spectra, t_exp=0.3s, t_cad=2.5s AO : AOon, several interruptions SJ : DALSAs - gb,ca, t_exp=0.3s, t_cad=0.5s Halpha SVHS videotape DATA : download of 27+28/11/2006 data to DLT tapes Mon Nov 27 : ciruses almost all over the sky in the morning holes between them in the afternoon moderate seeing SP : 5434 A: 0,45,60,53 degrees positions run: 500 spectra, t_exp=0.3s, t_cad=2.5s AO : only TT, several interruptions SJ : DALSAs - gb,ca, t_exp=0.3s, t_cad=0.5s Halpha SVHS videotape DATA : download of 26/11/2006 data to DLT tapes Sun Nov 26 : clear sky in the morning, later cirruses moderate seeing TESOS: 5434, series of scans: DC, 45,60degrees 101steps per 1.2mA per scan DC: with AO (2 interruptions) 45degrees: with TT (4 interruprions) 60degrees: without TT/AO (TT problems) ECHELLE+DALSA+VIDEO: adjustment, storing, trigger Sat Nov 25 : low clouds above VTT in the morning clear sky, bad seeing in the afternoon DALSA: final adjutment and full operation of 2 cameras for G-band and Ca II H SJ DATA : download of 22+23/11/2006 data to DLT tapes Fri Nov 24 : some cirruses, very bad seeing TESOS: alignment tests for 5434 A DALSA: transfer to SJ system - both SP : tests of the XEDAR B camera counts new data: G=6291 P=-7.672 5434 + central mask Thu Nov 23 : clear sky, right wind TESOS: 5434 - DC - 1run: 24 scans stored DATA : 24 scans, 5434, +/-100steps,delta=3steps, +/- 0.609A, delta=0.0012A, t_exp=50ms Wed Nov 22 : haze, some clouds, bad seeing, TESOS: small field, adjustment, testing with 5576, adjustment of 5434 filter, data merging problem with the filter order - solved VTT: drive problem - solved DATA: 8 scans, 5576, just for SW testing Tue Nov 21 : clouds, almost no blue sky, strong wind Mon Nov 20 : clouds, almost no blue sky, strong wind Sun Nov 19 : several cirruses, almost no blue sky Sat Nov 18 : several cirruses, hazy sky, east wind echelle: 5232+5434 setup - problems with grating reading offset (solved by Na lines + standard mask), XEDAR A camera - reading problems (bottom part of the chip) - unsolved final solution - ballo+XEDAR B at 5434 using 5232+5434 mask (upper slit shifted to the central position) - G=6594, P=-7.7 experience gained for future: start with Na lines + standard mask at 35.0 cm -> deriving the actual constants for the grating and predisperser formulae tesos: 5454 A filter installed in FilterPosition 3 sj: G-band filter found Fri Nov 17 : clear sky, good conditions echelle: 5576+6301/2 setup - problems with low light level different orders, 60+150microns slits, slit tilt, light path tested camera of the spectrograph focused decision to test 5232+5434 as in the year 2004 made to test the camera aging Thu Nov 16 : clouds, rain computers, VTT, TESOS, echelle procedure JR, 28/11/2006
