Pearson coefficients for the correlation of log (a_alig) with the log of different physical quantities.

Notes. In the diffuse and translucent ISM, a_alig is primarily driven by the gas pressure, not by the characteristics of the radiation field (direction, anisotropy factor, or intensity). An increasing intensity of the radiation field even tends to disalign grains by increasing FIR photon emission.
