Abstract

We present updates to the Union compilation, including several new datasets and new systematic error treatment. The dominant systematic error is calibration, particularly for supernovae with only two bands. We improve the cosmological constraints from the original Union compilation by about 10-30%, including systematic errors. However, no real constraint can be placed on w above redshift 1.

This work has been supported by the Office of Science, U.S. Department of Energy, through contract DE-AC02-05CH11231 and in part by NASA through grants associated with HST-GO-10496.
