Notes. We list the transitions, the telescope/instrument, the dates of observation, and the literature references for previously published data.

(a)

Teyssier et al. (2006) state that observations were carried out between September 2001 and February 2002. A search of the CSO archive database resulted in observations in February 2002 that could be linked to their paper.
