Abstract

We present pulse shapes of 87 pulsars at 4.85 GHz. Pulse widths and flux densities are measured. The frequency dependence of the profile shape and the pulse width is discussed. Our data base has been combined with other published data to generate flux spectra between 1.4 GHz and 5 GHz. The mean flux spectral index has a value -1.9. Our analysis shows that pulsar emission spectra are steeper at higher frequencies.
