XMM-Newton Multi-Target Visibility Checker

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 page.

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.



SIMBAD or NED Lookup

Please enter an object name to look it up in SIMBAD or NED;
Target Name   (eg; Abell 1750)
   
Please note; there is a 30 second timeout should SIMBAD or NED not respond.



Single Target Visibility

To calculate the visibility of a single target, please complete the following fields and "Submit" your request.

Target Details

Target Name   Target name or identifier for output (eg; Abell 1750)
RA   Decimal degrees or HH:MM:SS.S (eg: 13:30:52.5)
Dec   Decimal degrees or DD:MM:SS.S (eg: -01:50:27.0)

Visibility Details

Select either
Revolution Range First Revolution  default revolution range is current revolution (2740) to 3002
  Last Revolution
or
Date Range From Date  default is today
  To Date
 
Minimum visibility (minimum time the bin must be visible. Default is 5000 s)

   



Multiple Target Visibility

To calculate the visibility of mutiple targets, please complete the following fields and "Submit" your request.

Target Details

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.

  13:30:52.5 -01:50:27.0 Abell 1750  (colon separated)
  13 30 52.5 -01 50 27.0 Abell 1750  (space separated)
  13h30m52.5s -01d50'27.0" Abell 1750  (hms & d ' " format)
  202.71875 -1.84083 Abell 1750  (decimal degrees)

Visibility Details:

Select either:
Summary of visibility for each target (n. of visible revs, max & min) for the requested revolution range.
or
Revolution Range First Revolution  default revolution range is current revolution (2740) to 3002
  Last Revolution
or
Date Range From Date  default is today
  To Date
 
Minimum visibility (minimum time the bin must be visible. Default is 5000 s)
