Ulysses - SWICS - abundance ratios

ResourceID
spase://CNES/NumericalData/CDPP-AMDA/ULYSSES/SWICS/ulys-swi-rat

Description
Selected charge states and abundance ratios : Alpha particle speed: Repeated from previous archive for comparison. - C6+/C5+ and O7+/O6+ ratios: These two ratios are essentially redundant, with the former being ~10 times higher than the latter on average. At high values the O ratio is more reliable (because C5+ is getting rare) whereas at low values the C ratio is preferable (because O7+ gets rare). Low ratios are indicative of fast streams. - Fe/O abundance ratio: This is a proxy for the strength of the FIP fractionation if divided by the solar Fe/O ratio of ~0.05. - Average charge state of Fe: Weighted average of all charge states from Fe6+ to Fe16+, normally between 9 and 12 both in slow and in fast wind. High values are a good CME indicator. - Number of instrument cycles that were accumulated to obtain the 3-hour average value. Each instrument cycle takes 13 minutes, so values of 12-14 are normal, whereas low values should be considered as a warning.
