Changes in the new UPb DRS (“U_Pb_Geochronology3”)

There are some noteworthy improvements in the latest release of the UPb DRS (U_Pb_Geochronology3), so I thought I should post a description of what’s changed. One of the biggest changes is that flexibility has been added in which isotopes have been measured – previous versions required 206, 207, 208, 232, and 238 (with an option…
