[vsnet-sequence 12] V2400 Oph - corrected sequence



Berto was correct, 13.422/0.713 should indeed be part of this sequence. In fact I did intend it to be, but a slip of the finger brought in the slightly fainter 13.455/0.845. This mistake is now corrected. I have also replaced the original red star 9 (15.403/1.645) with 15.011/0.509, as per Berto'suggestion. The
final corrected sequence is available on the anonymous ftp server as

> Dear Bruce and interested readers,

> last night I had a look at my sequence brew for V2400 Oph and compared

> Two main differences though and I dare to push my preference here:

> 1. I would definitely include the star 13.42 (0.71) 2' E of V.
> It is not just closer to V2400 but also more blue than No 4 in your > list.

> 2. Star 15.01 (0.51), located at 171252-241232, is a bit further away
> from V than your No 9 but it is defintely blue-white and not red like
> No 9. It must be expected that if V2400 Oph fades slightly it will
> still be blue-hot.

> That was my promised feed-back on the sequence.

> Kind regards,
