J/PASJ/61/97        Proper motions with Subaru SDF           (Richmond+, 2009)

Proper motions with Subaru. I. Methods and a first sample in the Subaru Deep Field. Richmond M.W., Morokuma T., Doi M., Komiyama Y., Yasuda N., Okamura S., Gal-Yam A. <Publ. Astron. Soc. Jap., 61, 97-107 (2009)> =2009PASJ...61...97R

In this paper, we describe in detail our reduction and techniques to identify moving objects. We present a first sample of 99 stars with motions of high significance, and discuss briefly the populations from which they are likely drawn. Based on photometry and motions alone, we expect that 9 of the candidates may be white dwarfs. We also find a group of stars which may be extremely metal-poor subdwarfs in the halo. File Summary:
