cone: Executes a Cone Search-like query
cone is a utility to execute one of the
"Simple" positional DAL query operations on a remote server:
Simple Cone Search,
Simple Image Access (SIA) or
Simple Spectral Access (SSA).
The job it does is not very complicated: given a base URL for
a service of one of these types and values for the central position
and radius required, it assembles the query URL in the form required
for the relevant protocol, retrieves the result of the query,
and turns it into a table which can be operated on with the usual
STILTS pipeline operations.
