Detailed Description

SkyBoT Minor Planet Service Interface: --------------------------------------

A utility class for accessing the IMCCE Skybot ephemerides service. The service is called as part of the constructor for the object allowing easy access to the result data. Class methods also exist so a VO Client interface the same access to the data.

Class Methods: --------------

sb = voc_skybot (ra, dec, rsz, dsz, epoch)

count = voc_skybotNObjs (sb) str = voc_skybotStrAttr (sb, attrname, index) dval = voc_skybotDblAttr (sb, attrname, index)

Available Attributes: ---------------------

Example Usage: ---------------

1) Find bodies in a 900" radius around (0.0,0.0) on JD 2453939.123

VOCSkybot skybot = new VOCSkybot (0.0,0.0,900,2453939.123); for (int i=0; i < skybot.getNObjs(); i++) System.out.print ("Name: '" + sb.getStrAttr("name",i)+"' " + "RA: " + sb.getDblAttr("ra",i) + " " + "Dec: " + sb.getDblAttr("dec",i) + " " + "Mv: " + sb.getDblAttr("vmag",i) + " ");
