    Good, we'll go ahead with the correlation of 'E' as the
    round-about companion of 'G' (which was the reobs of 'C').
    There is a 4 month seperation between E and G, which is
    beyond the 3-30 day gap you preferred. Please let us know
    if that's going to be a problem. E *does* contain the
    source IC133, 'I' was without it.



The 4 month gap is not optimal, but it wont be a big problem.

    The next pair will be F and J, to be observed in '07. But
    I'm not sure which month we should aim for now. Can you
    clarify? The key we have for F is attached, as is the key
    for E. If i understand correctly, the key for E should be
    used for J. Please could you confirm?


Any date between December 06 and March 07 would be fine with me. And BB200J  schould be the same as BB200E.

Thanks,
Andreas

Hi Lisa,

I think correlating BB200E instead of BB200I would be the best option. I
checked the Tsys plots for BB200E and the observation was good. I can live
with not having IC133 in this observation. Re-observing BB200I would be too
much (it is already a re-observation of a re-observation).

Best regards,.
Andreas

Hi Lisa,<br>
<br>
I think correlating BB200E instead of BB200I would be the best option.
I checked the Tsys plots for BB200E and the observation was good. I can
live with not having IC133 in this observation. Re-observing BB200I would be too much (it is already a re-observation of a re-observation).<br>
