In order to retrieve seeing data over a specified date range, please choose this web link, but note at the moment it works only from within the ING web domain.

RoboDIMM seeing estimates have been shown to agree with those from other monitors observing at ORM. There is some evidence however that as the seeing becomes smaller than about 0.6 arcsec, RoboDIMM becomes increasingly insensitive and may display an overestimate in this case.
