Overview
Simple Cone Search (SCS) is an IVOA standard that enables discovery of catalog data based on celestial position. It provides a simple HTTP interface for performing spatial queries around a specified Right Ascension and Declination, returning all objects within a specified search radius.
- Cone search queries by celestial position (RA/DEC)
- Configurable search radius
- VOTable response format support
- Optional filtering by maximum records
- Verbosity level control for response detail

Query Parameters
The SCS service accepts the following parameters:
| Parameter | Type | Required | Description |
|---|---|---|---|
RA |
float | Required | Right Ascension of the search cone center in decimal degrees (0-360). |
DEC |
float | Required | Declination of the search cone center in decimal degrees (-90 to +90). |
SR |
float | Required | Search radius in degrees. Typically between 0.01 and 180 degrees. |
RESPONSEFORMAT |
string | Optional | The desired response format (default is VOTable). |
MAXREC |
integer | Optional | The maximum number of records to return. A value of 0 means unlimited. |
VERB |
integer | Optional | Verbosity level (1=minimal, 2=normal, 3=full). Default is 2. |
