Frank: The raw data (TRK-2-34) are in the first table below, the ODF's in the second. The raw data from G226X24A.TNF and G227C34A.TNF are both included in G227227A.ODF; this covers two-thirds of your gap. It's one-way, but tracking data nonetheless. There may be about an hour missing on the front end, but I'm willing to assume that was lost to some problem at the station. I have nothing in my notes to indicate problems which would have affected occultations, however. I don't have anything to indicate that there was tracking on day 226 between 19:25 and midnight, so that gap is probably real. Since raw data and the ODF's are collected using different algorithms, I doubt there was a pass that slipped through without our noticing. There is a lot of coverage, but it's not continuous.
