Singularity spectrum and log-normal fit for each ROI. Shown for each region of interest in the Musca cloud delimited in Fig. 22 are the singularity spectrum h↦D(h) of an ROI (in orange), a log-normal fitted approximation singularity spectrum (in blue; Eq. (9)), the obtained numerical values h_m and σ_h, and the error of the fit. The various values of h_m and σ_h for each ROI are also given in Table 1.
