low proper motions

Rix and I had the terrible realization that most of the 9 epochs of SDSS data that overlap Milky Way globular cluster Palomar 5 are in fact Apache Wheel data taken at low angular resolution for calibration purposes. So we will have to go to historical or HST data to perform the proper motion measurement. We made some inquiries about both.

We had some conversations with Sebastian Jester (MPIA) about finding quasars and halo giants by their low proper motions. He obtained the proper motion catalog developed in the SDSS multiply-imaged southern equatorial stripe and is looking at that now.
