Check the visibility of any location for the XMM-Newton Observatory with this tool.
There are three methods of checking visibility;
The output information can be reduced by specifying restrictions like range of revolutions and minimum visibility time for the target. The visibility is determined from a DataBase of Observable Bins (DBOB), each bin corresponding to a size of 2x2 degrees.
Further information about the XMM-Newton orbit details and viewing constraints as well as a description of the DBOB can be found on the XMM-Newton Orbit & Constraint Details
Details about the behaviour of the XMM-Newton background are given in the following Technical Note: The Behaviour of the XMM-Newton Background
For further information on the use of this tool and a description of the different parameters, please see our Vischeck How To

RA & Dec coordinates can be specified in several formats and all of the following examples can be processed.
Please note that sign + or - for Declination is mandatory
, otherwise one may get contradictory formats.
