It is estimated by the researchers that the cluster is 443 light-years away by using radio telescopes and is at odds with the measurements taken through the Hipparcos that shows the distance as 390 light-years.

Linking Hipparcos and ICRF2 is essential in order to uniformize the reference independently of whether the source is visible (HCRF) or not (ICRF).

These observations, re-analyzed with the Hipparcos Catalogue (ESA 1997), were then used to determine the Earth Orientation Parameters (EOP) at 5-day intervals, covering the interval 1899.7 -1992.0 (Vondrak et al., 1998; Vondrak et al., 2000; Ron and Vondrak, 2001).

We originally began observing HD199122 as a SPB based on its appearance in the list of such stars found through Hipparcos data examination by Koen (MNRAS, 321, 44, 2001).

As part of the calibration effort for the WIRE satellite, investigation of the Hipparcos database allowed stars of any given spectral type to be separated for magnitudes as faint as V=12.
