A Trustworthy and Simple Method to Determine Pulsar Distances and the Electron Distribution in the Galaxy

We present the model for determination of pulsar distances or average electron distribution using a method similar to the widely used dependence of A$_V$ on distances in different directions. To have reliable pulsar distances, we have used several natural requirements and distances of pulsar-calibrators. We have constructed dispersion measure-distance relations for pulsars in 48 different directions.
