dear all,
</p>
<p>
during this run, we observed the polar field and ran the extinction monitoring script 3 times a night. Almost all the time it seemed to be slightly above the standard curve and we concluded that these were photometric conditions. We wonder if , at some time, we can replace the curve with our own data. However, could the extinction also depend on season? We wonder if there are extinction report which are below the curve , done in one of the previous commisioning runs. It may be a good idea to make a plot with horizontally the date, and vertically the quantified, fitted, extintion value.
