Absolute magnitudes and slope parameters for 250,000 asteroids observed by Pan-STARRS PS1 - preliminary results

This web site contains a database of absolute magnitudes and slope parameters of numbered asteroids observed by the Pan-STARRS1 telescope from February 2011 until May 2012 within its 3π and Solar System surveys. Observations were obtained in 6 Sloan-like filters (g,r,i,z,y,w). The photometry used in this study was derived in the chip-stage of the image processing and only contains PSF-like (slow and untrailed) detections of a high photometric quality. Absolute magnitudes and slope parameters were derived by using both Bowell's (Bowell, 1989) and Muinonen's phase functions (Muinonen et al., 2010). Additionally, each value has its statistical uncertainty and systematic error derived.

Our Monte Carlo method and pipeline are described in details in a paper by Vereš, P., Jedicke, R., Fitzsimmons et al., 2015. Absolute magnitudes and slope parameters for 250,000 asteroids observed by Pan-STARRS PS1-Preliminary results. Icarus 261, 34-47. Arxiv version of paper.
