190	Thinning of pole-crossing occultations with S-G pre-smoothing	Huw Lewis	Ian Culverwell	"See Ticket #171 for initial queries about the thinner implementation of occultations crossing the +/-180 degree line and the pole. 

Investigations showed no problems in either case using Log or Lin thinning methods. For methods using Savitsky-Golay pre-smoothing, an outlier point was found for thinning longitude for cases where an occultation crosses the pole (see Figure 3 of attachement to #171). This geometry may be impossible for current LEO-GPS configurations, but a fix should be investigated."	defect	closed	minor	6.0	ropp_io	3.0	fixed	thinner, S-G
