Slightly wrong orbit file for edge cases

[bbuzz31]

If you run eof to grab the orbit file for this slc: S1A_IW_SLC__1SDV_20230106T235934_20230107T000001_046670_059804_D8E3.zip

It downloads this file: S1A_OPER_AUX_POEORB_OPOD_20230127T081807_V20230106T225942_20230108T005942.EOF

If you look closely, the orbit file starts on 1/6/2023 at 22:59:42, which is a bit later than the sensing start of 1/6/2023 at 22:59:34. I'm not sure what/if this has an effect downstream but thought it would be worth mentioning.

That also had me head scratching awhile... but it's actually hour 22 vs hour 23, so the orbit does cover the file. Might be easier to see like this:

In [1]: from apertools import parsers; from rich import print

In [2]: print(parsers.Sentinel("S1A_IW_SLC__1SDV_20230106T235934_20230107T000001_046670_059804_D8E3.zip"))
Sentinel(
    filename='S1A_IW_SLC__1SDV_20230106T235934_20230107T000001_046670_059804_D8E3.zip',
    start_time=datetime.datetime(2023, 1, 6, 23, 59, 34, tzinfo=datetime.timezone.utc),
    stop_time=datetime.datetime(2023, 1, 7, 0, 0, 1, tzinfo=datetime.timezone.utc),
    relative_orbit=48,
    polarization='DV',
    mission='S1A'
)

In [3]: print(parsers.SentinelOrbit("S1A_OPER_AUX_POEORB_OPOD_20230127T081807_V20230106T225942_20230108T005942.EOF"))
SentinelOrbit(
    filename='S1A_OPER_AUX_POEORB_OPOD_20230127T081807_V20230106T225942_20230108T005942.EOF',
    orbit_type='precise',
    start_time=datetime.datetime(2023, 1, 6, 22, 59, 42, tzinfo=datetime.timezone.utc),
    stop_time=datetime.datetime(2023, 1, 8, 0, 59, 42, tzinfo=datetime.timezone.utc)
)

@scottstanie sorry about that! Staring at too many orbits files too late in the day 😵‍💫
