ESP: power spectrum
Extremely nasty window function required careful deconvolution (Carretti, PhD thesis)
Convolved (cyan) and de-convolved (blue) P(k) from mag-lim. Catalogue (also shown in magenta is the deconvolved P(k) from M<-20 sample)
Lines show fits with simple phenom. model a la Peacock
Note strong effect of |W(k)|2
Impossible to go below 0.06 h Mpc-1, need e.g. Karhunen-Loeve approach (Szalay, this meeting)
