terra15
Read and write data from Terra15 DAS interrogators.
Terra15’s website can be found here
Note
Terra15 files contain GPS_time and posix_time arrays; DASCore uses GPS time. GPS timestamps can jitter, occasionally decrease between samples, and differ from the dT attribute, so by default (snap=("time",)) time is put on the grid spanning the first and last written GPS times, checked against the quartile times; where those sit more than dascore.config.max_shift steps off it, the times are kept as stored with a warning.
Unwritten trailing rows with zero-filled timestamps are excluded whether snapping is enabled or disabled. Passing snap=False preserves the written samples’ raw timestamps (snap_dims, the released spelling, is deprecated).
