The diffractive process ep→eXY, where Y denotes a proton or its low mass excitation with MY<1.6?GeV, is studied with the H1 experiment at HERA. The analysis is restricted to the phase space region of the photon virtuality 3?≤?Q2?≤?1600?GeV2, the square of the four-momentum transfer at the proton vertex |t|
