General Information . ... The conference is organized by the Sternberg Astronomical Institute (SAI) of Moscow University and the IAU Working group "Site-testing Instruments" . ... Use of site data in telescope operation and adaptive optics. ... Recent conferences on this subject (2007, 2008) demonstrated great interest of the community, hence the need for a new meeting. ... Unlike previous recent conferences, this meeting will cover all aspects of site monitoring for optical/IR astronomy. ...

In typical operation, Apache is started by the root user, and it switches to the user defined by the User directive to serve hits. ... If the logs directory is writeable (by a non-root user), someone could replace a log file with a symlink to some other system file, and then root might overwrite that file with arbitrary data. ...

... Previous: Why Indexing the Sky is Desirable . ... An alternative algorithm, proposed here, is based on covering the sky with pixels of approximately equal area, and assigning a unique integer to each pixel. ... For each table, the pixel code value corresponding to the central position (RA, Dec) of each source is computed and inserted into a new column called PCODE. ... This cannot be the primary index of a table since PCODE values are not necessarily unique: one pixel may contain more than one...

... For reliable estimation of the accuracy of asteroid CCD observations we usually consider from ten or more various NUMBERED MINOR PLANETS (NMPs) observed during several nigths per month (more then 50 positions). ... They can be considered as an indicator of accuracy of the CCD positional observations with given MPC code. ... For any NUMBERED minor planet the (O-C) values must be zero if the errors of observations and the errors of its theory are absent. ...
