The relationship between superconductivity and the CDW in underdoped Bi2201. Doped hole concentration dependence of the upper critical field H c2, H CDW (left axis) and T CDW (right axis). Error bars represent the uncertainty in the fit using WHH formula to obtain H c2 (Supplementary Fig. 5) and in defining the onset field H CDW and temperature T CDW
