VIII/12 Orion A Emission-Line Surveys (Jewell+ 1989) ================================================================================ Orion A Emission-Line Surveys from 200.7-202.3, 203.7-205.3, and 330.5-360.1 GHz Jewell P.R., Hollis J.M., Lovas F.J., Snyder L.E. =1989ApJS...70..833J ================================================================================ ADC_Keywords: Radio sources ; Surveys Description: This catalog comprised surveys of the Orion A molecular emission lines from 200.7-202.3, 203.7-205.3, and 330.5-360.1 GHz. These surveys were done by using the 12m radio telescope of the National Radio Astronomy Observatory (NRAO). For the 870microns (um) atmospheric window, about 160 distinct spectral features composed of nearly 180 lines were detected. For the other two bands 42 distinct, new spectral lines were detected. The new interstellar lines in the survey bands were tabulated in FITS format. This new data base would be a useful resource for further analyses of abundances and excitation of known Orion A species and for determining unidentified lines for use in molecule identification. The single-dish FITS format in FITS table extension was adopted to create this catalog. The data were tabulated in the order of Figures 1-39, including both the unshifted and shifted spectra in each figure (Jewell et al., 1989). Single Dish header parameters were represented in the table's header, and the data comprised the actual table in ASCII. Various FITS Tables keywords were given in great detail for describing the format of the table and how a computer program could read it.

The data images of the spectra were written in the exact order that the figures appear in the journal paper. The lower sideband (LSB) frequencies (in MHz) of the 75 tables were summarized in the following list (table number vs. LSB): No. LSB(MHz) No. LSB(MHz) No. LSB(MHz) ------------ ------------ ------------ 1 201003 26 339810 51 351810 2 201515 27 339800 52 353300 3 202027 28 343300 53 353310 4 333800 29 343310 54 353800 5 333810 30 343800 55 353880 6 334300 31 343810 56 354300 7 334310 32 344300 57 354310 8 334800 33 344310 58 355300 9 334810 34 344800 59 355310 10 335300 35 344810 60 355800 11 335310 36 345300 61 355810 12 335800 37 345310 62 356300 13 335810 38 345796 63 356310 14 336300 39 345806 64 357300 15 336310 40 349300 65 357290 16 337300 41 349310 66 357800 17 337310 42 349800 67 357810 18 337800 43 349810 68 358300 19 337810 44 350300 69 358310 20 338300 45 350310 70 358800 21 338310 46 350800 71 358810 22 338800 47 350810 72 359300 23 338810 48 351300 73 359310 24 339300 49 351310 74 359800 25 339310 50 351800 75 359810 ------------ ------------ ------------ Note the 75 FITS tables correspond to the Figures 1-39 of the paper.
