DET
DET records
include tag detection information. Some fields in this record only apply to certain
receiver models and tag types; these are indicated in the table where appropriate. Only detections
passing the filters listed in DET_FILTER records are included in DET records.
Detection Type Signal Strength Noise Quality Score
HR Yes Yes Yes
HR_SELF* No No Yes
PPM (decoder D1)** No No No
PPM (decoder D2)** Yes Yes No
PPM_SELF* No No No
* A HR_SELF or PPM_SELF detection is a detection of the receiver's own built-in transmitter.
** The HR2 receiver has two methods of decoding PPM transmissions. PPM transmissions may be
decoded by
one or both decoders; in either case, a single detection is reported in the Live Detections
Tab .
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
1
). 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.
1
Upon export to CSV format, all data records are automatically corrected for receiver clock drift by the Fathom software. Fathom
uses the difference between your receiver’s clock and the UTC time calculated from your PC clock at offload to calculate corrected
times for each record in the receiver log. If the receiver clock was also adjusted during deployment (for example, using an external
device to periodically send time corrections to a cabled receiver), then these adjustments are also used in the calculation of corrected
times.
