bottom_delim_bsm: Delimitate bottom phase of dive using brokenstick models
In SESman/rbl: Biologging tools for diving predators in R

Description Usage Arguments Examples

The bottom is defined as the dive period between the first brokenstick segment (descent) and the last brokenstick segment (ascent).

1	bottom_delim_bsm(time, depth = NULL, npts = 6)

`time`	time readings, sorted in chronological order.
`depth`	depth readings, sorted in chronological order.
`pts`	The number of points to use in the brokenstick model. The default (`npts = 6`) is used by CTD-SRDL tags (Sea Mammal Research unit, St Andrews University) to summarize dive profiles.
