D e s c r i p t i o n S C H M I C A T . S D F This file contains the information about all plates of the Tautenburg Schmidt telescope (focal length 4 m, field of view 3.3 * 3.3 square degrees) in standard data format (i.e. readable with every text editor). Plates with 2 half-fields or strongly separated exposures are registered as separate plates. The coordinates are normally given for the equinox of the day of observation. In the case of plates taken with objective-prism the given delta values are normally 15 arcminutes greater then those of the plate center. All values are taken from the original log-books. Missing data are filled with blanks. The plates 22a und 284a (not in the log-book) are registered as second plates under 22 und 284. The plate 390 also contains the exposure 393; 3589 contains 3581. The plate numbers 110, 231, 794 and 2583 have never been used. Each row of the file contains the following data (the number is the field length in byte): 4 :plate number 8 :right ascension of the plate center in hours: minutes:seconds e.g.: 00:00:00 6 :declination of the plate center in degrees: minutes (always with sign!!) e.g.: +00:00 7 :date of the beginning of the exposure: year, month, day e.g.: 89APR17 (CET) 5 :beginning of the exposure in hours:minutes (CET) e.g.: 00:00 6 :exposure time in minutes:seconds e.g.: 100:00 (in case of several exp. the longest one is given) 4 :information about the plate-filter combination 1 :0 = without wedge, 1 = with wedge 12 :up to 3 remarks (each with 4 byte) 3 :some special objects, e.g. comets, are numbered 7 :place where the plate is currently stored 1 :"*", if the plate is scanned Explanations of the plate-filter combinations: U = UG2 + ORWO ZU or AS or KODAK O B = GG13+ ORWO ZU or AS or KODAK O V = GG11+ KODAK D or G R = RG1 + KODAK E I = RG1 or RG2+ KODAK I-N NF= without filter WF= with filter, but not U,B,V,R,I PO= with polaroid The last three abbreviations NF, WF or PO are connected with: BS = blue-sensitive plate (O, AS, ZU) CO = Color- plate GS = green-sensitive plate (J) YS = yellow-sensitive plate (D, G, ZP1, ZO, AP, RO) RS = red-sensitive plate (E, NP27, ZP3, APS, H alpha) IS = infrared-sensitive plate Explanations of the remarks: TEST = test plate FOCE = plate for the determination of the correct focus HARE = Hartmann-test HALF = half-field (the other part of the plate contains an other half-field, so called "transfer plates") HAFI = with half-filter EXFO = extra- or intrafocal exposure NGUI = without moving the telescope or with high-speed moving MOVO = guided to a movable object (comet, minor planet) nEXP = n exposures, slightly separated (n=N for n>9) SSEX = short, slightly separated second exposure SCHR = Schraffier images OBPR = with the great 1/2 degree objective-prism WIDE = widened 20PR = only 20cm prism, rest of the corrector covered 30PR = only 30cm prism (00PR = no diameter registered) +20P = additional 20cm prism in front of the corrector +30P = additional 30cm prism (+00P = no diameter registered) PLNR = plate number (in the case of 22a and 284a) 2PLN = 2 plate numbers on the plate (390 + 393, 3589 + 3581) DEST = destroyed during or after exposure (light, drying, other experiments) FLCA = plate holder with flattening lens (TAUMOK 16 cm) AUTO = automatically guided Special objects: 1 = Halley 1986 III = 1982i 1P/1982 U1 2 = Wilson-Hubbard 1961 V = 1961d C/1961 O1 3 = Bowell 1982 I = 1980b C/1980 E1 4 = Austin 1982 VI = 1982g C/1982 M1 5 = Churyumov-Gerasimenko 1982 VIII = 1982f 67P 6 = IRAS-Araki-Alcock 1983 VII = 1983d C/1983 H1 7 = Bradfield 1987 XXIX = 1987s C/1987 P1 8 = West 1976 VI = 1975n C/1975 V1 9 = Schwassmann-Wachmann 1 1974 II 29P/1976 UR3 10 = Bradfield 1974 III = 1974b C/1974 C1 11 = Kobayashi-Berger-Milon 1975 IX = 1975h C/1975 N1 12 = Kohoutek 1973 XII = 1973f C/1973 E1 13 = Gehrels 2 1973 XI = 1973n 78P/1973 S1 14 = Bennett 1970 II = 1969i C/1969 Y1 15 = Abe 1970 XV = 1970g C/1970 N1 16 = Ikeya-Seki 1965 VIII = 1965f C/1965 S1 17 = Alcock 1965 IX = 1965h C/1965 S2 18 = Kearns-Kwee 1963 VIII = 1963d 59P/1963 Q1 19 = Pereyra 1963 V = 1963e C/1963 R1 20 = Alcock 1963 III = 1963b C/1963 F1 21 = West ? 22 = Sugano-Saigusa-Fujikawa 1983 V = 1983e C/1983 J1 23 = Austin 1990 V = 1989c1 C/1989 X1 24 = Levy 1990 XX = 1990c C/1989 K1 25 = Grigg-Skjellerup 1992 XVIII 26P 26 = Schuster 1992 XXVI = 1992n 106P/1992 O1 27 = Shoemaker-Levy 9 1994 X = 1993e D/1993 F2 28 = Hyakutakae C/1996 B2 29 = Hale-Bopp C/1995 O1 999 = Mond
