Exceptions Remarks
The units are automatically converted into meters, seconds, and radians from mm, years, and milli-arc seconds.
Parts per billion (ppb) are divided by one billion to make the Scaling constant term unitless.
A file of this format should be able to be found in the DynamicEarthData folder of a STK install that
is 12.7 or later (2023r2 or later). Specifically, the correct file in that folder should be named "ITRFDefns.txt".
