Hello,
I have a set of 42 hair snares that are sampled/deployed three times in three consecutive random subsets (w/o resampling) of 14 within a session (year) so that each snare has three sampling occasions within a session.
Question: when I construct the capture and trap files for secr modelling, should I
(i) code the trap file with usage , whereby each detector has three 1s and six 0s like this 111000000 and accordingly assign detections to one of 9 occurrences across the full set of traps
OR
(ii) consider this design as having three occurrences (each detector sampled three times within the session, just not all of them at once) and thus the trap file will only have trapID, X, Y fields and in the capture file detections will be coded to three occasions?
Thank you!
