Caveats
General Notes per Lynn Wilson Jan 2015: The solid-state telescope (SST) for Wind 3DP electrons returns a velocity distribution function containing 7 energy bins and 48 solid-angle bins. The automated CDF routine appears to remove all the following solid-angle bins: [7,8,9,15,31,32,33] = sun/anti-sun look directions, and [20,21,22,23,44,45,46,47] = low geometry factor bins (also correspond to the SST Thick anti-coincidence detector bins). The sun/anti-sun directions are removed to avoid X-ray and EUV contamination, which is often seen during solar flares. The onset looks exactly like the GOES X-ray observations, which is kind of fun but not what we want to look at. Unfortunately, these look directions can correspond to the magnetic field direction, which can limit the times when we would like to examine SEP events. General Notes per Lynn Wilson Jan 2015: Note that SST Open (e.g., wi_sopd_3dp_00000000_v01.cdf) software removes the following additional solid-angle bins: [0,1,24,25] = noisy. Additionally, SST Open has 9 energy channels from ~70 keV to ~6.7 or 7.1 MeV, depending on the mode the instrument is in. It does not appear that the routine mk_sosp_cdf.pro removes any of these ...bad... look directions, so that should be noted as well. General Notes per Lynn Wilson Jan 2015: Inside the radiation belts, both Foil and Open saturate and suffer from penetrating particles. The instruments are not shielded, so they can only provide relative changes when in these regions. General Notes per Lynn Wilson Jan 2015: The data below all look like they are in units of number flux or # cm-2 s-1 sr-1 eV-1. I believe the CDAWeb units are correct for most of these.
