`image`	top-of-atmosphere landsat reflectance image
`Ts`	land surface temperature in K. See surfaceTemperature()
`LAI`	rasterLayer with Leaf Area Index. See LAI()
`albedo`	broandband surface albedo. See albedo()
`Z.om`	momentum roughness lenght. See momentumRoughnessLength()
`n`	number of pair of anchors pixels to calculate
`aoi`	area of interest to limit the search. If waterOptions(autoAOI) == TRUE, It'll use aoi object from .GlobalEnv
`anchors.method`	method for the selection of anchor pixels. "random" for random selection of hot and cold candidates according to CITRA-MCB method, or "best" for selecting the best candidates. And "flexible" for method with soft limits to the anchor pixel conditions.
`WeatherStation`	Optional. WeatherStation data at the satellite overpass. Should be a waterWeatherStation object calculated using read.WSdata and MTL file.
`plots`	Logical. If TRUE will plot position of anchors points selected. Points in red are selected hot pixels, blue are the cold ones and the black represents the position of the Weather Station
`deltaTemp`	deltaTemp for method "CITRA-MCBs" or "CITRA-MCBr"
`minDist`	minimun distance allowed for two anchor pixels of the same type (in meters).
`WSbuffer`	maximun distante to the Weather Station (in meters).
`verbose`	Logical. If TRUE will print aditional data to console
