The units of this plot are rad/rt(Hz). I've no idea why it just says magnitude.
This is a known thing (at least to me and Rana), so it's not just you. When you put in some points like your PD Spec, the units disappear, and I've never figured out how to get them back while keeping the points. Thanks for putting the units in your entry though. If anyone else does know how to get the units to 'stick' where they're supposed to be, that would be helpful.
