Data Set Abstract |
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 352 files that represented the digitized spectra from
plate material. In some cases, the 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. For this data, no distinction about
'reduction' is distinguished for this process. The data
cover the date range from 1985 October 17 through 1986 December
12. |
