I was adding tags to Satellite tracking telescope integrated program in Matlab and included the frames tag with 24 questions.
Then I noticed there also existed eci with 5 questions, and ecef with 2 questions that are also tagged eci.
It seems that those 5 could easily be covered by the frames tag and that we don't need the two more specific ones, very often people want to convert between one and the other.
Shall I just retag the five with frames and let the eci and ecef sort-of disappear when the clock strikes twelve?
update: I'm going to open up this question a little by mentioning that the coordinates tag is also being actively used in this constellation of concepts:
- Accuracy of ECI (J2000) to ECEF (WGS84) for a LEO satellite only accounting for Earth Rotation (tagged neither with eci, ecef nor frame!)
- Accuracy of ECEF to ECI, using just GAST (tagged neither with eci, ecef nor frame!)
- Rotation matrix from J2000 to ITRF2008
- LVLH to ECI Conversion
