Coona, we have FLD files.

So, it looks like we're almost there! I've constructed 15 .fld files which have enough objects for two AAOmega visits each and they're looking okay!! (Only spotted one entry with 60.000 in the arcsecs column!)
We've (Shanks, Edge and I) eye-balled the guide stars (and they look like stars) and the LRG candidates (which look like very faint little red dots) and even some potential z~3 QSOs (which also look like stars!).

The ELG run starts on Sunday evening and there is still a (helluva) lot that can go wrong between now and the start of our run but I'm feeling reasonably sorted.

Gierlinski gave what I thought was a very good (and nicely timed) seminar on "Variability spectra of accreting black holes". Essentially taking at High Mass X-ray Binaries (HMXB), seeing how their spectra change from a "soft" to "hard" state, calculate a rms/mean value of the variability versus energy (I think) and see what this can tell us about what the BH and the accretion disk are doing. Anyway, bottom line was the models seemed to fit the data well but a couple of key features are seen at 20keV where data is still poor.
