Fig. 13.
The AJJ′ coefficients of an isotropically pumped SiO maser at B = 1 G as a function of the magnetic field propagation direction angle cosθ. The different panels give the (a) J = 1−0, (b) J = 2−1, and (c) J = 3−2 transitions. Plots are given for different log(R/gΩ). The LTE solutions (constant over cosθ) are indicated with a dotted line.
