[ascl:2504.032] DMCalc: In-band dispersion measure of pulsars calculator
Krishnakumar, M. A.; Manoharan, P. K.; Joshi, B. C.; Girgaonkar, R.; Desai, S.; Bagchi, M.; Nobleson, K.; Dey, L.; Susobhanan, A.; Susarla, S. C.; Surnis, M. P.; Maan, Y.; Gopakumar, A.; Basu, A.; Batra, N. D.; Choudhary, A.; De, K.; Gupta, Y.; Naidu, A. K.; Pathak, D.; Singha, J.; Prabu, T.

DMCalc estimates the Dispersion Measure (DM) of wide-band pulsar data in psrfits format. It uses PSRCHIVE (ascl:1105.014) tools to get ToAs and then uses TEMPO2 (ascl:1210.015) for DM fitting. A median absolute deviation (MAD) based ToA rejection algorithm is implemented in the code to remove large outlier ToAs using Huber Regression. Although the code has been used for analyzing uGMRT wide-band data, DMCalc can in principle be used for any pulsar dataset.
