Fig. 2
Pixel-to-pixel comparison of the NIR and MIR column density data for the cloud B.
The dashed line shows the one-to-one correlation. The data show correlation below
mag, above which the NIR
data starts to underestimate extinction compared to the MIR data. The offset
of ~5 mag in the range 
mag originates from
the spatial filtering of the MIR technique.
