    EURONEAR - Tools - MASDS

Description: MASDS is the acronym for "Mega Archive Search of Double Stars".
It searches for double stars from the Washington Double Star (WDS) catalog in the Mega Archive (15 million images by Mar 2018).
Input: Object WDSID name or the WDS Discoverer code.
Output: List of images possible to hold the double star(s), including: name of the archieve/instrument, image ID, observing date/time (start), exposure time (s), some magnitude limit for the telescope/instrument, filter (plus eventually other comments from observer) and the distance between the object and the camera center (in degrees) with a percentage score.
Optional: The exact position of the double star(s) can be overlaid in the camera field by pushing the button "Position in CCD field".
Warning: Only a part of the fields are suported right now by this tool. The supported instruments (Mega-Archive) are growing continuously.


Current archieve info:

Searched object(s):
Please enter WDSID (ex: 13276+0655) or WDS Discoverer code (ex: STF 2727).
Searching for two or more objects is also possible, please separate them in a few lines.

   


Raw text output
Chose raw output mode to receive a CSV style output. Otherwise, a HTML table output will be produced.

Safety search border (deg):
