Low-frequency wideband timing of InPTA pulsars observed with the uGMRT

Published in Monthly Noticed of the Royal Astronomical Society, 2022

Application of the wideband timing method by Tim Pennucci for low-frequency data from the GMRT. This method allows us to simultaneously measure the pulse time of arrival and the dispersion measure for a pulsar observation while dealing with frequency-dependent profile evolution.
