Astrometric reference flag: This is a recommended astrometric reference star, having good Tycho astrometric quality, and not recognised as double.

Trigonometric parallax: 0.04550 arcsec
Standard error of the parallax: 0.00280 arcsec

Proper motion components (epoch J1991.25, ICRS)
(Data is from the ACT catalog)
RA:-0.58545 arcsec/yr
Dec:+0.34480 arcsec/yr

Standard errors of the proper motion components
RA:0.00437 arcsec
Dec:0.00459 arcsec

Number of accepted data points: 66
Goodness-of-fit parameter, F2: 1.35

Hipparcos catalog number: 78527

Astrometric quality flag: 1 (very high).
Signal-to-noise ratio of the star image, Fs: 9.6


Photometric Data
Mean Bt magnitude: 4.654
Standard error: 0.002
Mean Vt magnitude: 4.064
Standard error: 0.002

Source of photometric data: The Bt,Vt data are median values, rather than de-censored mean values (mainly relevant for bright stars with Bt<=8.5 mag and Vt<=8.0 mag).

Johnson B-V colour index: 0.542
Standard error: 0.002

Previously known or suspected variability: None.

Variability of the Tycho measurements: Variability suspected in the Tycho data; this may be due to intrinsic variability since no correlation with position angle was evident. No thorough investigation has been carried out to eliminate other reasons intrinsic to the Tycho measurements.

Unresolved duplicity status: An investigation was carried out on the Tycho data, but no indication of duplicity was found.

Answer 2

I don't have anything to add. and I don't think that it should be able to have a website to get tall the detais. Only if you have a stargasing software with the catalogs of the double stars you should be able to have all the info.

Simply I wanted to comgratulate David S for his time, effort and comprehensive answer.

David you deserve the 10 points.:)

Keep on the good job:)
