Fourier (solid lines) and wavelet (symbols) power spectra of the NGC 2264 region. Before fitting a P(k) =A k^γ relation (dashed curve), the corrected power spectra are subtracted by the noise level (plateau at the end of the original power spectrum, dotted horizontal green line) and divided by the empirical SPIRE 250 μm beam. The power spectra present two bumps, located at 1.4 and 0.1 pc (dot-dashed vertical blue lines). The intermediate scale chosento separate the three NGC 2264 subregions is indicated by a dot-dashed vertical red line.
