mergeVisibilityAndManualBlindTimes

Description

Function to merge manual blind times with blind times from visibility table. For further processing the radar (visibility) and manual blind times have to be merged with the function ‘mergeVisibilityAndManualBlindTimes’. This function will add a blind time type to the radar/visibility blind times. Blind times during the block time (usually 60s) at the beginning of each protocol are given the type 'protocolChange', the rest of the radar blind times are given the type “visibility”. After that the visibility and manual blind times will be merged. In case manual blind times and radar blind times are overlapping, radar blind times with type “visibility” will be overwritten, but not radar blind times with type “protocolChange”.

Usage

mergeVisibilityAndManualBlindTimes(
  visibilityData,
  manualBlindTimes = NULL,
  protocolData
)

Arguments

visibilityData

dataframe with the visibility data from the data list created by the function ‘extractDBData’.

manualBlindTimes

dataframe with the manual blind times created by the function ‘loadManualBlindTimes’.

protocolData

dataframe with the protocol data from the data list created by the function ‘extractDBData’ or a subset of it created by the function ‘filterProtocolData’.

Value

dataframe with overall blind times
