Estimate true phase rms from the cross-spectrum variance. see Petrov, Roddier and Aime, JOSAA vol 3, N.5, may 1986 p 634. and Petrov's Thesis, p. 50 ff. I replace the piecewise interpolation usually used by a polynomial approximation of the function: if z=log10(y), then z=(C[1]*X^7+C[2]*X^6+C[3]*X^5+C[4]*X^4+C[5]*X^3+C[6]*X^2+C[7]*X+C[8]) and y=10^z. where C[01]= 2.71918080109099 C[02]=-17.1901043936273 C[03]= 45.0654103760899 C[04]=-63.4441678243197 C[05]= 52.3098941426378 C[06]=-25.8090699917488 C[07]= 7.84352873962491 C[08]=-1.57308595820081 This interpolation is valid in the range x=[0.1,1.74413]. Error is 1% everywhere except above x=1.73 where it is 10% Below x=0.1: y=x Above x=M_PI/sqrt(3.0), y = blanking (impossible value) Above x=1.74413, we take: y=0.691/(pi/sqrt(3.0)-x)

The routine create a column in the output table with the same name and units as the one in the input table. It is filled with an average of the signal over all DITs, considering the column REJECTION_FLAG if present (non-zero means frame is rejected). This averaging is performed independently for the ntel tel (or base or triplet). The output table shall thus contain ntel rows while the input table shall contain ntel*NDIT rows.
Note that this routine is not optimized for performance and thus shall not be used on the FT tables.
