Description

StarDICE is a photometric calibration experiment attempting to
establish NIST-traceable spectrophotometric standard stars for the
upcoming LSST supernova survey. Since the last LSST-France meeting,
the experiment has resumed observations after upgrades in the data
acquisition, and a thorough measurement campain of the instrument
transmission curves using a dedicated instrument called monoDICE.

In this contribution we intend to present the monoDICE measurement
results and review the improvements in the analysis. We then discuss
the progress and perspectives for the new survey.
