# Flux density measurements for 32 pulsars in the 20 cm band

## TL;DR

This paper reports new flux density measurements at 20 cm for 32 pulsars using the Parkes telescope, updating pulsar data and analyzing measurement biases and methods.

## Contribution

It provides the first flux density measurements at 20 cm for these pulsars and compares different measurement schemes, including interference effects.

## Key findings

- Flux densities vary significantly between measurement methods.
- Radio-frequency interference biases flux density measurements.
- Updated pulse profiles enhance pulsar data accuracy.

## Abstract

Flux density measurements provide fundamental observational parameters that describe a pulsar. In the current pulsar catalogue, 27% of radio pulsars have no flux density measurement in the 20 cm observing band. Here, we present the first measurements of the flux densities in this band for 32 pulsars observed using the Parkes radio telescope and provide updated pulse profiles for these pulsars. We have used both archival and new observations to make these measurements. Various schemes exist for measuring flux densities. We show how the flux densities measured vary between these methods and how the presence of radio-frequency-interference will bias flux density measurements
