+ * This extraction strategy gets applied when guides are used to calculate the collimation length. The instrument
+ * parameter file contains the information about the number of guides to use. The guide data itself is fetched

  * @param inOutWS: a matrix workspace
  * @param L1: the distance between sample and source
  * @param collimationLengthCorrection: The correction to get the collimation length
