Dear NTT team/Olivier,

I include here the OB, finding chart and this readme file for the DDT proposal 266.B-5637(A).

I apologise for any stupidities in the OB - but I'm sure you'll let me know if there are any unresolved issues!

When acquiring the object, it is more important to get the target itself centred on the slit than the radio galaxy Pic A itself (in case of a small error in slit PA. I have asked for two red exposures and three blue ones since you advised me against the use of the dichroic.

I was not sure that this is the best order sorting filter for the red arm - please change this if there is a better one - GG375 seems a bit short...


Thanks a lot and regards, Bob...
