Dataset of blob detections in PSP/WISPR Encounters E01--E25 generated using a YOLOv11s-OBB detection model, including image coordinates, estimated 3D locations, and unique track IDs.

The final catalog contains one row for each blob detection associated with a track lasting at least 2 hours. The id_blob column assigns a unique identifier to each blob detected within an individual image (e.g., if three blobs are present in an image, they are labelled 0, 1, and 2). The catalog also records the observation date (date), image filename (file_name), and Parker Solar Probe encounter (id_orbit). The image coordinates of each blob (x_coord, y_coord), its position angle (central_angle) and elongation (elong), together with the corresponding FITS filename (fits_file) and observation time (datetime), are provided. The spacecraft heliocentric distance (distance_solar_radii), the apparent solar radius (rsun_arc), and the spacecraft position and velocity in heliographic and heliocentric inertial coordinates (HGLN_OBS_psp, HGLT_OBS_psp, HCIX_OBS, HCIY_OBS, HCIZ_OBS, HCIX_VOB, HCIY_VOB, HCIZ_VOB) are also included. Assuming that each blob lies on the Thomson surface, the estimated heliographic Stonyhurst (blob_lon_hgs, blob_lat_hgs) and Carrington (blob_lon_carr, blob_lat_carr) coordinates are computed. The columns r2 and ratios provide the projected radial distance and the normalized radial position of each blob within the WISPR field of view. Finally, the track_id column assigns a unique identifier to each tracked blob, allowing the same feature to be followed across consecutive images.
