GSAS-II, probably the most comprehensive user of pdCIF, does not use _pd_meas_angle_2theta. Based on that single datapoint, and there having been no reply to the original email, I will make pd_meas_angle_2theta an alias to pd_meas_2theta_scan.

An easy one: pd_meas_angle_2theta appears in a series of datanames that describe the 4-axis diffractometer settings of a sample, however, pd_meas_2theta_scan already covers the position of the 2 theta axis.  Is this a simple duplicate that can be deprecated?  Who among you outputs/reads each of these datanames?
