Regge models for proton structure function with and without a hard Pomeron contribution are compared with all available data in the region W>3 GeV, Q2≤3000 GeV2

. It is shown that the data do not support a hard Pomeron term in

amplitude. Moreover, the data support the idea that the soft Pomeron, either is a double pole with
