Quantifying Period Uncertainty in X-ray Pulsars with Poisson-Limited Data

Autor: Singhal, Akshat, Jain, Ishan, Bala, Suman, Bhalerao, Varun

There have been significant developments in the period estimation tools and methods for analysing high energy pulsars in the past few decades. However, these tools lack well-standardised methods for calculating uncertainties in period estimation and
