Notes. The super-indices 1 and 2 indicate the first and the second extinction layer, respectively. The mean extinction for the stars corresponding to each extinction map is indicated by Āλ. The associated standard deviation, σĀλ, shows the variation of the extinction within a layer for a given band. The symbols Δstat Āλ and Δsyst Āλ indicate the average statistical uncertainty computed using a Jackknife algorithm for a given band and layer, and the systematic uncertainty of the corresponding extinction map, respectively. In all the cases the first H1 corresponds to the extinction layer obtained using the JH bands, whereas the second one was computed using HKs. The results obtained for NSD W are less reliable due to bad data quality caused by bad weather conditions.
