The shape of integrated profiles is certainly one of the most important characteristics of pulsars. Integrated profiles and their frequency dependence are indications for the spatial structure of the emission region and of the structure of the neutron star's magnetic field. At present there exists already a variety of papers presenting multifrequency integrated pulse profiles of pulsars, e.g. Morris et al. (1981), Hankins & Rickett (1986), Kuzmin et al. (1986), Izvekova et al. (1989), Izvekova et al. (1994), and Seiradakis et al. (1995).
Our catalogue is specific in covering a wider frequency range, including low-frequency profiles and many frequencies, i.e. 102, 230, 408, 610, 1400, 4700, and 10500 MHz. Low-frequency profiles of pulsars with large dispersion measures were corrected for interstellar scattering (see Kuzmin & Izvekova 1993). An important additional feature of this catalogue is that the profiles are aligned in time. This allows one to obtain correct identifications of individual components and their frequency evolution, an important feature for the analysis of the spatial structure of the emitting region and the magnetic field.
