NAME SOHO SWAN Derived Cometary Water Production Rates Collection
TYPE Data
DESCRIPTION This data collection contains derived water production rates for numerous comets observed by the SOHO SWAN instrument from 1996 to 2021. Multiple measurements were made for each comet through a single perihelion passage and some comets were observed over multiple epochs. The production rates were derived by modeling the observed distribution of atomic hydrogen in the comae of the comets. This version corrects issues discovered in the previous version of the water_c_1995_o1_hale_bopp table.
