Here is an answer from Tomi - "the reflectivity improvement is basically in the coating process, a better process gas tuning, power, mask shape, rotation speed, etc. All the coating related parameters." |

@ivezic or @cclaver or @sandrinethomas -- can we get the additional final reviewer approval? |

This update includes the M2 reflectivity curve based on witness sample measurements from M2 coating run in July 2019
The M2 curve is getting a bit better than the June 2019 update.
