>Yamaoka did not give any errors for his reductions;
Oh, sorry. The fitting error for each measurement is about 0".3.
And, the dispersion between four measurements is around (or smaller
than) 0s.01 and 0".1. It is because I gave 0s.001 and 0".01 digit.
I think the positions given by Gianluca, Arne and me agree very well,
and also with USNO-A2.0 position.
>Since Yamaoka-san notes a fainter companion,

But every DSS image shows the USNO star far brighter than a dim star I
noted. I guess this dim star will not affect large for the photometry
even on quietience.
Sincerely Yours,
