"Eloi, Eloi, lama sabachthani?"

What a frustrating day. Have realised that the "all-singing-all-dancing" npt code doesn't seem to calculate xi(sigma,pi) correctly!! There seems to be an order of magnitude difference between DR pairs which leads to ~unity values of xi and high wp(sigma)'s. ARGH!!! Really not sure what to do. Just when I thought there was only a couple more bridges to cross, this happens!!
If I cannae figure oot what's up with the npt code for the DRs (and RRs????!) then I might just have to resort to what I wanted to do this time last year!! Fook!!!!

On the wires today were Padmanabhan's (Princeton) and Blake's (UBC) photo-z LRG Power spectra papers (astro-ph/0605302 and 0605303). They are basically looking at exactly the same things (angular power spectra with LRGs, photo-z's being estimated from training sets and then some "fancy maths" to get the 3D power spectrum). Well, if correct and they have a handle on all their systematics, photometeric calibrations and other selection issues, then these are (very) powerful pieces of work. However, what I don't understand straight off the bat is how, if you are claiming, at best delta_z = 0.03 on your photo-z, can you then split your sample into bins of 0.05 width (e.g. 0.45 < z <0.50) ????
