Satellite: Ulysses Experiment: HISCALE (Heliosphere Instrument for Spectra, Composition and Anisotropy at Low Energies) Principal Investigator: Dr. Louis J. Lanzerotti, AT&T Bell Laboratories Data Set Contact: Prof. Thomas P. Armstrong, University of Kansas Data Set Description: This ASCII data set was provided via Wide World Web by the HISCALE team at the University of Kansas and includes spin-averaged hourly counting rates from the five sensors of the HISCALE instrument during the interplanetary phase of the Ulysses mission, also including the Jovian encounter from 1992-02-02 to 1992-02-16. The sensors include the two Low-Energy Foil Spectrometers (LEFS60 and LEFS150) at 60 and 150 degrees to the spacecraft spin axis, the two Low-Energy Magnetic Spectrometers (LEMS30 and LEMS120) at 30 and 120 degrees, and the Composition Aperture (CA 60), also called WARTD, at 60 degrees. The HISCALE experiment and data channels used in this data set are described in Lanzerotti et al, Astron. Astrophy. Suppl. Ser. 92, 349, 1992. Further details about the instrumentation and data set processing can be found in the HISCALE Data Analysis Handbook, available in hardcopy form from NSSDC. This data set is available on-line here in the NSSDC Anonymous FTP directory. See NSSDC's Ulysses flight project page under URL http://nssdc.gsfc.nasa.gov/space/ for further details and updates.
