Figure 4a. The defocus in arcseconds of blur on the image plane is shown as a function of time for the night of August 14. Arrows mark the times at which the telescope focus was manually changed. The labels show the magnitude of the changes made. The squares show measurements of the defocus just prior to and after manual focus changes. ... Below I will show clear indications of errors in the secondary motions which are probably contributing significantly to focus errrors in the telescope. ...

... The Seasons . ... Section #1 Stargazers and Skywatchers described the observed motion of the Sun across the sky, in different seasons of the year. ... If the Earth's axis were perpendicular to the ecliptic, as in the drawings here, the Sun's position in the sky would be halfway between the celestial poles, and its daily path, seen from any point on Earth, would stay exactly the same, day after day. Each point on Earth would be carried around the axis AB once a day. ... The Sun and Seasons . ...

Next: VLT Data Quality Control . Up: Dataflow and Scheduling . ... A key challenge for ESO's Very Large Telescope (VLT) will be responding to changing observing conditions in order to maximize the scientific productivity of the observatory. For queued observations, the nightly scheduling will be performed by staff astronomers using an Operational Toolkit. ... The MTS, developed by ESO, will be used to create candidate lists of observations (queues) based on different scheduling criteria. ...

... First, there is a set of residual plots against airmass for each night. ... If you reply ``YES'', it will show you some plots intended to help you distinguish between time-dependent extinction and time-dependent zero-point drift. ... Figure: Sample drift plot . The principle behind these plots is that time-dependent extinction produces errors (and hence, we hope, residuals) that are proportional to airmass; but instrumental drift produces residuals uncorrelated with airmass. ...
