Abstract
THERE have been several attempts to estimate the distances of the pulsars using theoretically based models for the free electron distribution in the interstellar medium. A different approach is to make a crude first order approximation that the pulsars are immersed in a uniform dispersing medium, calculate the distances and directions of all pulsars on this assumption and compare the results with the properties of other galactic components, particularly supernova remnants, which would appear to have a common origin. Discrepancies revealed in this comparison may then be used to refine the assumed model of the interstellar medium and improve the distance scale.
