slv.measurements.mobile.gps.fill_gps_gaps_with_horel(data, site, lin_gps, max_clock_offset_s=3.0, tolerance='15s')

Georeference the rows the lin GPS could not, using the horel logger’s 5-s fixes.

136 days have LGR data but no lin GPS file at all (it was never archived) and many more have partial outages — ~754 on-track hours, most of it 2019-2023. The horel CR1000 logger recorded position throughout. Its own clock runs 1-20 s ahead of GPS time, but read_horel_cr1000() puts its fixes on GPS time (from the receiver’s time of day), so both sides are on GPS time and it can stand in wherever the Pi clock is trustworthy (clock_checked_days()). Adds gps_source ("lin" / "horel") so the filled rows can be dropped or compared at load time.
