ACE Cosmic Ray Isotope Spectrometer (CRIS) intensities and counts, for each of 7 energy bins for each of 24 elements (Z=5, boron, to Z=28, nickel) at 1-hour time resolution. Overall energy ranges covered go from 49-172 MeV/n for boron to 130-496 MeV/n for nickel. Calibrated science quality data. Parameter segments below address intensities but not also the count rates included in the data set. The data are accessible via ftp in HDF and CDF from the ACE Science Center and CDAWeb, respectively, and in ASCII format from the value-added interfaces at those sites. Daily averaged L2 fluxes and rates are also available from these access paths. The "parameter keys" given below are as used by CDAWeb.

ACE Solar Isotope Spectrometer (SIS) hourly intensities and count rates, for each of 14 elements (He,C,N,O,Ne,Na,Mg,Al,Si,S,Ar,Ca,Fe,Ni).in each of 8 energy bins. Overall energy ranges covered go from 3.4-41 MeV/n for helium to 10.5-168 MeV/n for iron. These are calibrated science quality data. The data are accessible via ftp in HDF and CDF from the ACE Science Center and CDAWeb, respectively, and in ASCII format from the value-added interfaces at those sites. The "parameter keys" given below are as used by CDAWeb.

Daily-averaged species-separated energy spectra derived from the Pulse Height Analyzer. Data consist of counts and fluxes of each of six species (He, C, O, Ne, Si, Fe) in each of 12 energy bins.

12sec-averaged and spin-averaged count rates from all detectors.

The Ultra Low Energy Isotope Spectrometer measures Ion Fluxes over the Charge Range from H through Ni from about 20 keV/nucleon to 10 MeV/nucleon, thus covering both Suprathermal and Energetic Particle Energy Ranges. Exploratory Measurements of Ultra-Heavy Species (Mass Range above Ni) will also be performed in a more limited Energy Range near 0.5 MeV/nucleon. ULEIS will be studying the Elemental and Isotopic Composition of Solar Energetic Particles, and the Mechanisms by which these Particles are energized in the Solar Corona. ULEIS will also investigate Mechanisms by which Supersonic Interplanetary Shock Waves energize Ions. To avoid Confusion and Misunderstanding, it is recommended that Users consult with the appropriate ACE Team Members before publishing Work derived from the Data. The ACE Team has worked hard to ensure that the Level 2 Data are free from Errors, but the Team cannot accept Responsibility for Erroneous Data, or for Misunderstandings about how the Data may be used. This is especially true if the appropriate ACE Team Members are not consulted before Publication. At the very least, Preprints should be forwarded to the ACE Team before Publication.
