HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT       #4766 PERIOD COVERED: 5am January 6 - 5am January 7, 2009 (DOY 006/1000z-007/1000z) OBSERVATIONS SCHEDULED FGS 11789 An Astrometric Calibration of Population II Distance Indicators 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, ...Continue Reading

The dominant error in globular cluster age determinations is the uncertain Population II distance scale. We propose to use ...Continue Reading
