cds-question@unistra.frpulsarsradio-astronomyWe present integrated pulse profiles at 5GHz for 71 pulsars, including eight millisecond pulsars (MSPs), obtained using the Shanghai Tian Ma Radio Telescope. Mean flux densities and pulse widths are measured. For 19 normal pulsars and one MSP, these are the first detections at 5GHz --and for a further 19, including five MPSs, the profiles have a better signal-to-noise ratio than previous observations. Mean flux density spectra between 400MHz and 9GHz are presented for 27 pulsars and correlations of power-law spectral index are found with characteristic age, radio pseudo-luminosity, and spin-down luminosity. Mode changing was detected in five pulsars. The separation between the main pulse and interpulse is shown to be frequency independent for six pulsars, but a frequency dependence of the relative intensity of the main pulse and interpulse is found. The frequency dependence of component separations is investigated for 20 pulsars, and three groups are found: in seven cases, the separation between the outmost leading and trailing components decreases with frequency, roughly in agreement with radius-to-frequency mapping; in 11 cases, the separation is nearly constant; in the remaining two cases, the separation between the outmost components increases with frequency. We obtain the correlations of pulse widths with pulsar period and estimate the core widths of 23 multicomponent profiles and conal widths of 17 multicomponent profiles at 5GHz using Gaussian fitting, and we discuss the width-period relationship at 5GHz compared with the results at at 1.0 and 8.6GHz.2019ApJ...874...64Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/874/64CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/psr : ATNF Pulsar Catalogue (Manchester+, 2005)VII/156 : Catalog of 558 Pulsars (Taylor+ 1993)VII/189 : Catalog of Pulsars (Taylor+ 1995)J/MNRAS/273/411 : Multifrequency fluxes of 280 pulsars (Lorimer+ 1995)J/MNRAS/301/235 : Multifrequency polarimetry of 300 pulsars (Gould+, 1998)J/ApJS/121/171 : Arecibo polarimetry of 98 pulsars (Weisberg+, 1999)J/A+AS/147/195 : Pulsar spectra of radio emission (Maron+, 2000)J/MNRAS/335/275 : Parkes Multi-Beam Pulsar Survey new PSR (Morris+, 2002)J/MNRAS/342/1299 : Parkes Multi-Beam Pulsar Survey.
