6. While writing this work, I became acquainted with the review W. Ketterle, A.P. Chikkatur, and C. Raman, in Atomic Physics XVII, edited by Ennio Arimondo, Paolo De Natale, and Massimo Inguscio AIP Conf. Proc. No. 551 (AIP, Melville, NY, 2000), pp. 337-355; e-print cond-mat/0010375. There the temperature effect was considered; however, the authors found this contribution negligible, because of a background subtraction method used in Ref. [5], at variance with the results of this paper.
