Date: Sun, 1 Aug 99 21:16:30 MES From: rdscholz@aip.de (Ralf Scholz) To: pai@unix.mail.virginia.edu, thenry@recons.harvard.edu Subject: List of hpm stars for parallax program Cc: mike@ast.cam.ac.uk, rdscholz@aip.de Hi Phil and Todd, here is the list of stars to be included in your parallax program. There are apmpm numbers (from our pilot program of the new high proper motion survey, presented at the NStars Workshop) and apm_ numbers (from the next about 70 survey fields). The UKST field number (fno) is also given. I decided to make a selection based on the proper motion, i.e. only those APM discoveries are included, for which the pm exceeds 0.7 arcsec/yr. In addition, there are three stars without apm_no (and with proper motions not as large), which were discovered as nearby candidates in our Calar Alto spectroscopic observations (also presented at the NStars Workshop). All positions, proper motions and photometry are from APM measurements of UKST plates, except the proper motions of the non-APM stars, which were taken from the NLTT. Spectral types are from SAAO observations. From the stars with sp. types only those were included, for which the spectroscopic parallax turned out to be less than 25 pc. Please, let me know about the progress of your measurements, and whether you need more stars (e.g. bright newly discovered stars with 0.5 < pm < 0.7 arcsec/yr). Can you tell me again, how faint you can go? I got an e-mail from Rene Mendez, who told me about a parallax program at CTIO for stars with 12 < V < 22. I assume, this is your program (?). Best wishes Ralf P.S.: Please, let me know if you need finding charts. the list of 21 hpm stars: ------------------------- alpha,delta (J2000) Epoch mux muy R Bj-R apm_no. fno SpType spectr. notes plx.
