The solid lines are fits of the equation $\log y=-Ax+B$ to the data with E>0.2. Bottom: summary of the fitted A parameters for all the models of the study. The blue asterisks correspond to E_H-K values and the red diamonds to E_J-H values. The error bars represent the 1 $\sigma$ error of the fits. The horizontal lines give the error-weighted average of the data points. The average values are also printed in the frames.

The ratio is measured at the point of maximum E_H-K in each cloud. The approximate peak values corresponding the $\xi$ values of 0.1, 0.27, 0.5, and 0.75 are 0.5, 0.6, 0.9, and 1.1. The number of the model and the corresponding $\xi$ value are marked in the frames. The dotted lines show the ratio if the scattered flux is neglected (see Sect. 3.3).

The different panels correspond to different values of $\xi$ parameter. The red plus signs correspond to $M_{\rm low}=4.0$ (models 1-12), blue asterisks to $M_{\rm low}=4.5$ (models 13-24), and purple diamonds to $M_{\rm low}=5.0$ (models 25-36).

The apparent extinction is as defined by Eq. (1). The data are for models 5-8, with the model number and the corresponding $\xi$ values marked in the frames. The dotted lines show the corresponding histograms if the scattered light is neglected. (See Sect. 3.3) Bottom: the same for $A^{\rm a}_{J} / A^{\rm a}_{H}$ .

The observed masses are calculated from the E_H-K values by assuming the foreground screen geometry and Galactic gas-to-dust ratio. The dotted line shows the one-to-one ratio. Bottom: the fraction of detected clouds, i.e. the completeness function, in models 5-8 (dotted, dashed, dash-dotted, and solid lines). The masses are given in solar masses.

The fraction refers to the scattered flux in the pixel divided by the total flux in that pixel (i.e. not by the total unattenuated flux). The solid lines show the median value of the relation for different $A_{\rm V}$ values in model 5 ( $\xi =0.1$ ). For comparison, the dashed line shows the median ratio for model 8 ( $\xi =0.75$ ).
