Description

The NANOGrav 12.5-year wideband data set (public release "12yv4") is the supplemental data set accompanying Alam et al. 2021, "The NANOGrav 12.5 yr Data Set: Wideband Timing of 47 Millisecond Pulsars," The Astrophysical Journal Supplement Series, 252, 5, DOI 10.3847/1538-4365/abc6a1. It contains wideband pulse times of arrival, models describing frequency-dependent template profiles, pulsar timing models,  timing residuals, and clock files.

Details about the contents of these files are contained in NANOGrav_12yv4_wideband/README, as well as in NANOGrav_12yv4_wideband/wideband/README.wideband. The narrowband version of this dataset (published in Alam et al. 2021, ApJS, 252, 4, DOI: 10.3847/1538-4365/abc6a0) can be found at Zenodo DOI: 10.5281/zenodo.4312297. Both the narrowband and wideband data sets are also available at data.nanograv.org.
