In 2002 HST produced a highly precise parallax for RR Lyrae. That measurement resulted in an absolute magnitude, M(V)= 0.61+/-0.11, a useful result, judged by the over ten refereed citations each year since. It is, however, unsatisfactory to have the direct, parallax-based, distance scale of Population II variables based on a single star. We propose, therefore, to obtain the parallaxes of four additional RR Lyrae stars and two Population II Cepheids, or W Vir stars. The Population II Cepheids lie with the RR Lyrae stars on a common K-band Period-Luminosity relation. Using these parallaxes to inform that relationship, we anticipate a zero-point error of 0.04 magnitude. This result should greatly strengthen confidence in the Population II distance scale and increase our understanding of RR Lyrae star and Pop II Cepheid astrophysics.

For this proposed study we will obtain 15 orbits of astrometric data with FGS 1r for each RRL, kappa Pav, and associated reference stars, and 25 orbits for VY Pyx, all spread over 2 years. Given 2-gyro pointing restrictions, it may not always be possible to sample the parallactic ellipse at times of maximum parallax factor. The ecliptic latitude of most of these targets renders their parallactic ellipse rather round, increasing the value of uniform sampling over the times of the year when available. Essentially, we obtain parallax information at every epoch. We are in essence sampling the perturbation orbit of the Earth, an orbit whose shape is known with almost infinite precision from the various JPL ephemerides. Each of the orbits will include 3-4 measures of the primary target and several measures of each reference star, completely filling the 40-50 minute visibility period. Each visit will include multiple POS mode (fringe tracking) observations of the prime science target RLL and kappa Pav and from 5 to 10 astrometric reference stars. The first observation set for each target will include fringe scans (TRANS mode) of each RRL and Pop II Cepheid to assess the magnitude of any companion effects on fringe tracking (POS mode) measurements and on eventual absolute magnitude, M$_V$ and M$_K$ determinations. Should previously unseen companions be detected, each subsequent observation sequence would include fringe scans with which to correct both position and measured Pop II science target magnitude. Co-Is will obtain classification spectra and BVRI photometry for all reference stars and Washington-DDO photometry to confirm reference stars luminosity class. We essentially model a volume of space when carrying out this astrometry. The more prior information we have about our reference frame, the more accurate our final result.
