Arguments

cProject

The name of the project, e.g., Big Farm 2

Name

The name of the modeler, e.g., Jane Doe

nTurbine

the number of turbines

HazDiam

diameter of turbine blades (in m) (optional)

HazRadm

radius of turbine blades (in m) (optional)

HazRadKm

radius of turbine blades (in km) (optional)

HzKM2

Hazardous area around each turbine (in km^2) (can be supplied directly or calculated via the optional arguments HazDiam, HazRadm, or HazRadKm)

CntMin

Duration of one pre-construction observation, in minutes (optional)

CntHr

Duration of one pre-construction observation, in hours (can be supplied directly or calculated via the optional argument CntMin)

EOutMin

Number of Eagle carcasses observed during PCMM surveys. (Defaults to -1 if PCMM not performed)

PCMMsurveys

Number of turbines surveyed during each PCMM survey event. Can be prorated for partially-surveyed turbines. (Defaults to 0 if PCMM not performed)

PCMMhrs

Number of daylight hours in PCMM survey period (Defaults to 0 if PCMM not performed)

Oprate

Average annual operational rate of turbines. Defaults to 1

CprHrKM2

Total surveyed hours * hazardous area surveyed in post-construction mortality monitoring (Can be supplied directly or calculated via the optional arguments PCMMsurveys and PCMMhrs)

ExpSvy

A data frame containing strata-wise (seasonal) data for eagle minutes (EMin), number of surveys (nCnt), size of a survey (CntKM2), and daylight hours (DayLtHr). Can be created manually or generated automatically by EagleWizard(). EMin, nCnt, and CntKM2 default to -1, 0, and 0 if pre-construction surveys were not performed, but DayLtHr must be supplied. Use DayLen() to calculate annual or seasonal daylight hours.

CPrPriors

Collision probability priors, either USFWS or Bay. Defaults to USFWS. If neither, custom priors must be provided.

AddTot

Add strata for total (TRUE) or not (FALSE)

aPriCpr

Alpha parameter for the exposure prior. Must be supplied if neither USFWS nor Bay priors are selected.

bPriCpr

Beta parameter for the exposure prior. Must be supplied if neither USFWS nor Bay priors are selected.
