IHW COMET HALLEY REDUCED SPECTROSCOPIC OBSERVATIONS V1.0

NASA's International Halley Watch (IHW) has created a Comet Halley Archive. The collection of data spans the full wavelength range as submitted by scientists to the IHW. The observations belong to one of the following Disciplines: Amateur, Astrometry, Infrared Studies, Large-Scale Phenomena, Meteor Studies, Near-Nucleus Studies, Photometry and Polarimetry, Radio Studies, and Spectroscopy and Spectrophotometry. The data collected by these nine disciplines were augmented by Spacecraft measurements. The data were submitted to IHW, but the evaluation and selection for the Archive has been the primary responsibility of the Discipline Specialist Teams for each network in cooperation with the Lead Center. The Spectroscopy and Spectrophotometry Network collected 2732 files of data which were classified as 'reduced', which means that at least wavelength is calibrated and in some cases flux as well. Some data on non-Halley targets for the spectroscopic observations can be grouped according to 'laboratory' calibration, dark, bias, flatfield, sky, and photometric standards. In the first category, a large number of 'arcs' and 'lamps' were used as follows: HE-NE, TH-AR, NE-AR, CU-AR, CU-NE, Thorium, Tungsten, Quartz, and Rubidium. For the 'sky' observers used the twilight, moonlight, and blank sky. The most common 'photometric' standards were stars, but observers also included other comets (Hartley-Goode), asteroids (Ceres), reflection nebulae (R8), and emission nebulae (NGC1982, NGC7000). A list of these stellar calibration targets follows: HD 140283, HD 184711, HD89688, HD102870, HD120086, HD13974, HD219188, HD 25680, HD 19445, HD18803, HD30455, HD26912, SAO 1280, HZ15, CD-22 7696, GD 190, GC5106, GC2188, GC2192, G19113213, G 99-37, L745-46A, Feige 15, Feige 56, Landolt 98, Landolt 92, Van Beuren, RHO ORION, CHI 1 ORION, 29 PI LEO. These data consisted of both one and two dimensional data covering the date range from 1984 December 23 through 1988 February 17.
