How can I change the scale of a skyplot?

How can I acknowledge NED if it has been useful in my research?

• Q.: How can I change the scale of a skyplot?
  A.: If you are accessing NED via the VT-100 interface, a scroll bar gives the size of the window. Set it between 0 and 250 arcminutes.

  If you are accessing NED from the World Wide Web, the default scale is that of the POSS and SERC/ESO Sky Surveys. To change that, click the "No" radio button, then enter you desired scale in arcsec/mm in the box. A convenient scale in arcsec/mm for viewing plots on your screen is the search radius in arcminutes that you used for your object search. The allowed range is 0.1 to 130 arcsec/mm.

  Q.: How can I acknowledge NED if it has been useful in my research?

  If your research benefits from the use of NED, we would appreciate the following acknowledgement in your paper:

  This research has made use of the NASA/IPAC Extragalactic Database (NED) which is operated by the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration.

  When citing NED within a paper, you may insert the following statement as a footnote:

  The NASA/IPAC Extragalactic Database (NED) is operated by the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration.

  We would also appreciate receiving a preprint or reprint of any publication acknowledging NED. Please send them to
