However, the same authors (Ikeda and Kitamura 2009) obtained $n\simeq -2.3\pm 0.3$ even for C$^{18}$O cores (its critical density $\sim 10^3{\rm cm}^{-3}$) in OMC-1 region in the Orion A cloud.

One of the reasons why large increase in the mass/flux ratio is favored is understood as follows: There have been a long-standing ``magnetic flux problem of stars'' in which the magnetic flux of, say, $1M_\odot$ main-sequence star $\Phi\sim XX{\rm G cm^2}$ is much smaller than that of the parent cloud $\Phi\sim XX{\rm G cm^2}$. The magnetic flux must be reduced in the star formation process. If the mass-flux ratio increases much in these density range, this might resolve the magnetic flux problem of stars.
