Usage

siteEstimate(
  tFirst,
  tSecond,
  type,
  twl,
  degElevation,
  method = "gamma",
  parms = c(3.3, 0.8),
  xlim = c(-180, 180),
  ylim = c(-90, 90),
  res = c(0.5, 0.5)
)

Arguments

`tFirst`	vector of sunrise/sunset times (e.g. 2008-12-01 08:30).
`tSecond`	vector of of sunrise/sunset times (e.g. 2008-12-01 17:30).
`type`	vector of either 1 or 2, defining `tFirst` as sunrise or sunset respectively.
`twl`	data.frame containing twilights and at least `tFirst`, `tSecond` and `type`
`degElevation`	the sun elevation angle (in degrees) that defines twilight (e.g. -6 for "civil twilight"). Either a single value, a `vector`.
`method`	`character` string; only `gamma` and `log-normal` are implemented.
`parms`	a `vector` describing the two parameters of the error density distribution (defined by `method`).
`xlim`	the longitudinal boundaries for which the likelihood will be calculated.
`ylim`	the latitudinal boundaries for which the likelihood will be calculated.
`res`	the spatial resolution in degrees.
