Error in Figure
Error in Table
In the original publication, there was a mistake in Tables 11–13 as published. The names of the detectors in row 5 (“PolRatio1”) and in row 6 (“PolRatio2”) are incomplete. The corrected Table 11, Table 12 and Table 13 appears below.
The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
