note

All Lanczos-vector calculations were performed with three to five iterations of the finite-lattice algorithm and a maximum of 200-300 states. Four Lanczos vectors were used as target states. All calculations were performed with open boundary conditions. A Parzen filter was used to minimize edge effects for the calculation of correlation functions.

note
-
For all finite-size extrapolations a polynomial in 1/N was used, where the 1/N term was excluded. This is the correct finite-size scaling for the S=1 chain (Ref. 24).

leg measurements on a thin sample (d≈μm) allowed for a considerable improvement of the background determination with respect to Refs. 10 and 11. Details will be published elsewhere.
