Download Workflow

It analyzes images from CAFOS instrument in Calar Alto Observatory. It uses SkyBot catalog in order to identify objects in the Solar System. It includes a double check to avoid objets that are not asteroids (comparing with USNO and 2MASS catalogs).

The result is a VOTable of asteroids

Inputs (4)

Name	Description
min_id	The workflow will retrieve the data in the range (min_id, latest id), being latest id the lastest id in the database.
pathToSaveFiles	Path where votables from sextractor will be stored. The path must include the last bar.
threshold	Threshold for sextractor. If this input is not provided the workflow will use the default value in the macro_template.
FWHM	Full width at half maximum of the PSF (Point Spread Function) for sextractor. If this input is not provided the workflow will use the default value in the macro_template.

Processors (5)

Name	Type	Description
Get_info_from_Cafos_and_Skybot	workflow	Create an VOTable with asteroids from CAHA observatory. It needs as input the minimun id that will be used to decide which data is retrieved from Cafos. In particular, you will the retrieve from min_id to the latest id in the database. The observatory id is fixed to CAHA.
