DIAG_HR2
DIAG_HR2 records contain HR2 diagnostic information. They are generated according to the
logging interval selected in the Sensor Logging tab in Fathom.
Field Description
Device Time (UTC) UTC date and time of the data according to the receiver’s clock (the
uncorrected time).
Time Date and time of the data following correction for receiver clock drift
(the corrected time)). The time offset of this time from UTC is indic-
ated in the “Time Offset (h)” column.
Time Offset (h) Offset from UTC time, in hours, of the value in the “Time” column.
The time offset is as selected when the receiver log was exported to
Fathom CSV format using the Fathom software.
Time Correction (s) The difference between uncorrected (“Device Time (UTC)”) and cor-
rected (“Time”) times.
Model Receiver model that generated the data in this record.
Serial Number Serial number of the receiver that generated the data in this record.
Tilt (degrees) HR2 receiver tilt angle (degrees from vertical), sampled at time of
logging
HR Noise (dB) HR (170 kHz channel) noise (dB), sampled at time of logging
HR Accepted Detec-
tions
Number of HR detections passing the filter criteria described in
DET_FILTER, since the previous DIAG_HR2 record
HR Rejected Detections Number of HR detections rejected by the filter criteria described in
DET_FILTER, since the previous DIAG_HR2 record
PPM Pings (D1) Number of PPM pings recorded by decoder D1* since the previous
DIAG_HR2 record
PPM Detections (D1) Number of PPM detections decoded by decoder D1* since the pre-
cious DIAG_HR2 record
PPM Pings (D2) Number of PPM pings recorded by decoder D2* since the previous
DIAG_HR2 record
PPM Detections (D2) Number of PPM detections decoded by decoder D2* since the pre-
cious DIAG_HR2 record
PPM Noise (dB) PPM (180 kHz channel) noise (dB), sampled at time of logging
