Observing Request Statistics February-July 1994 (1Dec93) (from CTIO, NOAO Newsletter No. 36, 1 December 1993) The total number of requests for telescope time received this semester 216, which is the largest number ever. Demand is up mainly on the 4-m, due to the return of the f/8 secondary (we hope!) and to the availability of the new PFCCD and corrector. Demand on the other telescopes is more or less stable. On the 1.5-m, demand for spectroscopy is down and imaging is up. This does not seem to be due to particular instrumental developments. The requests for time on the Schmidt were for CCD only; although we had expected heavy demand for the CCD we did not expect the plate requests to be zero. 4-meter Telescope: 167 nights available Requests Nights Requested Dark Bright Dark Bright Instrument Nights % 0 2 0 7 ASCAP 7 1.7 12 12 41 39 Argus 80 19.8 0 1 0 1 CF/CCD 102 25.2 3 12 11 45 Ech/CCD 56 13.9 0 1 0 3 IR/Phot 3 0.7 16 1 47 2 PF/CCD 49 12.1 4 3 16 9 RF-P 25 6.2 2 3 8 14 Visitor 22 5.4 0 15 0 59 OSIRIS 59 14.6 __ __ ___ ___ ___ ____ 64 56 213 191 404 100% Now Last Semester Semester Before Last No. of requests 120 107 108 No. of nights requested 404 355 362 Oversubscription 2.42 2.23 2.18 Average request 3.37 3.32 3.35 ______________________________________ 1.5-m Telescope: 170 nights available Requests Nights Requested Dark Bright Dark Bright Instruments Nights % 3 2 16 15 SCAP 31 9.1 13 3 79 7 CF/CCD 86 25.3 7 5 28 27 CS/CCD 55 16.2 0 9 0 46 Ech/CCD 46 13.5 0 1 0 9 IR/IRS 9 2.6 1 2 6 7 IR/Phot 13 3.8 2 16 0 76 OSIRIS 76 7.1 __ __ ___ ___ ___ ____ 26 41 138 202 340 100% Now Last Semester Semester Before Last No. of requests 67 69 68 No. of nights requested 340 301 366 Oversubscription 2.00 1.80 2.09 Average request 5.07 4.36 5.38 _____________________________________ 1-m Telescope: 173 nights available Requests Nights Requested Dark Bright Dark Bright Instruments Nights % 7 8 59 114 ASCAP 173 91.5 2 2 9 7 CS/2DF 16 8.5 _ __ __ ___ ___ ____ 9 10 68 121 189 100% Now Last Semester Semester Before Last No. of requests 19 13 19 No. of nights requested 189 101 164 Oversubscription 1.09 0.57 0.92 Average request 9.95 7.77 8.63 _______________________________________ 0.9-m Telescope: 168 nights available Requests Nights Requested Dark Bright Dark Bright Instruments Nights % 27 9 166 54 CF/CCD 220 100% Now Last Semester Semester Before Last No. of requests 36 36 41 No. of nights requested 220 207 258 Oversubscription 1.31 1.21 1.54 Average request 6.11 5.75 6.29 ________________________________________ Schmidt Telescope: 108 nights available CF/CCD 16 req. for 133 nights 100% Now Last Semester Semester Before Last No. of requests 16 18 10 No. of nights requested 133 104 89 Oversubscription 1.23 0.96 0.83 Average request 8.31 5.78 8.90 _______________________________________ 0.6-m Telescope: 181 nights available ASCAP 2 req. for 32 nights 69.6 No. of requests 3 Visitor 1 req. for 14 nights 30.4 No. of nights requested 46 _ __ ___ 3 46 100% Oversubscription 0.25 Average request 15.33 Jay Elias
