How to do?

Another way to get properties is to use the SsODNet.datacloud Webservice.

Examples:

• Diameters and albedos of dwarf planet Ceres
• Osculating elements of asteroids Pallas, Juno and Vesta from ASTORB
• Colors of asteroid Camilla

The datacloud service may also accept a list of target names to retrieve their data in a single request. The list of targets must be provided as a text file (unicode UTF-8 format) containing a name per line (example) or a JSON array (example). This file may be downloadable by the SsODNet server from an URL provided through the -name argument of the datacloud HTTP request, or may be submitted to the SsODNet server through a POST request (parameter = targets). In that case, the -name argument must be left empty.

Examples to retrieve the diameters and albedos of a list of targets:

• from an URL: demo
• POST method with curl (target list):

curl -F "targets=@target_list.json" \
 "https://ssp.imcce.fr/webservices/ssodnet/api/datacloud.php?-name=&-resource=diamalbedo&-mime=json&-from=SsODNetDoc" \
 -o diamalbedo.json

To discover the collections that make up SsODNet.datacloud, you must use the reserved keyword collection.

• all collections
• a specific collection (colors)

To know which bibliographic references have been used to populate the collections or a given collection, you must use the reserved keyword bibref.

• bibliographic references of all collections
• bibliographic references of a specific collection (colors)

To list the collections that contain properties for a given SSO, you must use the reserved keyword list.

• list of collections that contain properties of asteroid (85) Io.
• list of collections that contain properties of asteroids Pallas, Juno and Vesta

To get the properties of a given SSO, you must provide the name of the collection, or use the optional reserved keyword all to get all its properties.

• all properties for dwarf planet Ceres
• all diameter and albedo values for dwarf planet Ceres
