DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION Data Set Overview : This data set consists of documentation regarding 45 spectra obtained by various amateur astronomers as part of the International Halley Watch (IHW) Amateur Observations Network. The FITS headers and PDS labels included document the observational parameters of the spectra obtained. The spectra themselves were photographic. The plates have not been digitized or otherwise included directly in this PDS archive. The IHW archive volume documentation notes: The spectra listed were made with both prism and grating spectrographs in a variety of modes. These spectra are perhaps the only ones in the IHW archive which cover the full range of visual wavelength in one record. A few spectra extend into the photographic infrared.
