Mike alerted me to check several errors. Unexpected, since as I usually
inspect the report before sending it off.
I enter the IOD lines into HeavenSat's "Optical Measurements" and check
track and time offsets for consistency.
Obviously I didn't check 23936, as the second pos is 1 h R.A. off, and
should read
23936 96 029E   5919   201907282153345   57 15 0203195+455407 39
A typo - my paper notes from the reductions were OK.

My camera only records time to the second, and I calibrate it by taking 3-5
exposures of "Time The Sat" screens, and use an average. Hence my IOD
entries for accuracy are (usually) "57" (0.5 s). So there are possibilites
of 1 s jumps in my track times.

I use a 2 s self-timer to reduce shaking when I take satellite tracks, and
thus see no possibility to improve accuracy using a stopwatch.

The 43224 obs look OK to me. Finally, as Mike remarked, the 40539 times are
completely reversed - obviously I only eye-balled the intervals between
points ! Should be :
40539 15 015B   5919   20190727221640    57 15 0120452+375026 39
40539 15 015B   5919   20190727221642    57 15 0124600+383854 39
40539 15 015B   5919   20190727221649    57 15 0141218+413011 39
40539 15 015B   5919   20190727221651    57 15 0146074+421617 39
