Method Detail

getRa

double getRa()
      throws IOException

Get central right ascension for the current row's cone search request in degrees.

Returns:

right ascension

Throws:

IOException

getDec

double getDec()
       throws IOException

Get central declination for the current row's cone search request in degrees.

Returns:

declination

Throws:

IOException

getRadius

double getRadius()
          throws IOException

Get search radius for the current row's cone search request in degrees.

Returns:

search radius

Throws:

IOException

getIndex

long getIndex()
       throws IOException

Get the index in the underlying table to which the current row relates. The identity of this underlying table is not specified by this interface, but must be understood by the creator and user of instances. In particular, the return value does not necessarily increment by one for each call to next.

Returns:

row index

Throws:

IOException
