TL;DR: Pan-STARRS1 has carried out a set of distinct synoptic imaging sky surveys including the 3ππ$ Steradian Survey and the Medium Deep Survey in 5 bands as mentioned in this paper.

TL;DR: In this paper, the authors presented a catalogue of astrophysical data of 520 Galactic open clusters, for which at least three most probable members (18 on average) could be identified in the ASCC-2.5, based on the Tycho-2 observations from the Hipparcos mission.

TL;DR: In this article, the authors present the details of the photometric and astrometric calibration of the Pan-STARRS1 $3\pi$ Survey. The photometric goals were to reduce the systematic effects introduced by the camera and detectors, and to place all of the observations onto a photometric system with consistent zero points over the entire area surveyed, the ~30,000 square degrees north of $\delta$ = -30 degrees.

TL;DR: The 2nd version of the Catalogue of Radial Velocities with Astrometric Data (CRVAD-2) as mentioned in this paper is the result of the cross-identification of stars from the All-Sky Compiled Catalogue 2.5 million stars (ASCC-2.5) with other recently published radial velocity lists and catalogues, which includes accurate J2000 equatorial coordinates, proper motions and trigonometric parallaxes in the Hipparcos system, spectral types, radial velocities (RVs), multiplicity and variability flags for 549

TL;DR: The catalogue PPM-Extended (PPMX) as discussed by the authors consists of a survey complete down to RU = 12.8i n the magnitude system of UCAC2; additional stars of high-precision proper motions and all other stars from GSC 1.2 identified in 2MASS.
