SOHO Charge, Element, and Isotope Analysis System (CELIAS) Solar Extreme-Ultra-Violet Monitor (SEM) Daily Data in CDF Format

The data include daily average raw count rates in Channels 1 - 3 and First Order (26 - 34 nm, average of Ch1 and Ch3) and Central Order (0.1 - 50 nm, Ch2) photon fluxes, as well as SOHO Heliocentric location and distance. This CDF dataset was converted from the original ASCII dataset at the SOHO Archive soho.nascom.nasa.gov/data/archive.html. The original ASCII dataset Version 4 Science Product Release Notes are available at lasp.colorado.edu/eve/data_access/eve_data/lasp_soho_sem_data/long/LASP_SOHO_SEM_release_notes_v4.pdf.
