Notes. For PDS 37 the reduced χ2[d.o.f.] (degrees of freedom) for the best-fit models a, b, and c are 10[11], 16[10], and 10[10], respectively, while for PDS 27, the corresponing values for the best-fit models a and b are 10[12] and 12[11], respectively. Both visibilities and closure phases were taken into account.
