***** File OBSVINFO.TXT This directory contains information about the observatories and telescopes which contributed data to the IHW Archive. The principal file to which the Archive user may wish to refer is OBSCODES.TXT; this document contains quite specific information about each of the contributing observatories. Included in OBSCODES.TXT are tables listing SYSTEM Codes, Observatory names, Telescope/Instrument descriptions, and geographic locations. The SYSTEM Codes are particularly important because they allow the user to search various of the indices in this Archive for a particular observatory/telescope's data. The files called COUNTRY.TXT, IAU.TXT, and NOIAU.TXT are supporting documents which contain information which was important in the assignment of SYSTEM Codes by the IHW. However, the actual SYSTEM Codes, as well as the set of procedures the IHW used in assigning them, are contained only in the OBSCODES.TXT file.
