Table information for 'rob_spoca_ch.tracking'

General

Table Description: SPoCA coronal holes tracking

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: *** SPoCA Coronal Hole *** This service provides a catalog of Coronal Holes obtained with the Spatial Possibilitistic Clustering Algorithm (SPoCA). Level 2 AIA 19.3nm images (calibrated and corrected for degradation) are used, at a cadence of one AIA image every 6 hours. Only coronal holes older than three days are being reported. Bounding box and characteristics such as areas and pixel intensity statistics, on AIA 19.3nm and HMI magnetogram images are provided.
