Investigation of the errors in SDSS proper-motion measurements using samples of quasars
Investigation of the errors in SDSS proper-motion measurements using samples of quasars
2011/10/17
We investigate in detail the probability distribution function (pdf) of the proper-motion measurement errors in the SDSS+USNO-B proper-motion catalog of \citet{mun04} using clean quasar samples. The p...
Accurate Group Delay Measurement for Radial Velocity Instruments Using the Dispersed Fixed Delay Interferometer Method
Radial Velocity Dispersed Interferometer Method
2011/9/30
The Dispersed Fixed Delay Interferometer (DFDI) method is attractive for its low cost, compact size and multi-object capability in precision radial velocity (RV) measurements. The phase shift of fring...
