For the record

Correction: Because of a reporting error, the Radio Tracks column yesterday gave a wrong first name for former WBIX-AM station owner Bradford C. Bleidt.

Correction: Because of a reporting error, the number of NBA teams Dan Dickau has played for was incorrect in a story concerning his contract with the Celtics in Tuesday's Sports section. He has played for four teams.

Clarification: A story in Monday's Health/Science section about the ''patient navigator" program at Massachusetts General Hospital, designed to help women who have had abnormal mammograms navigate the medical system, was unclear about Debra Crowley's employer. Crowley works for the Geiger Gibson Community Health Center, whose navigator program operates under a grant from Mass. General and the Avon Foundation.
