 .. note ::
 
-    In the MATLAB version of ``ATaCR``, the "Angle from H1" (Figure 4 in the manual) corresponds to a counter-clockwise rotation of H1 and H2, and the orientation is chosen at the lowest phase. Here, the angle corresponds to a clockwise rotation and the estimate is chosen to lie between 0 and 180 degrees. There is therefore a 225-degree difference between those two estimates, and the plots are mirrored.
+    In the MATLAB version of ``ATaCR``, the "Angle from H1" (Figure 4 in the manual) corresponds to a counter-clockwise rotation of H1 and H2. Here, the angle corresponds to a clockwise rotation and the estimate is chosen to lie within +/- 90 degrees from a phase value of 0. Furthermore, we use a circular mean (as opposed to a linear mean) to calculate the phase, and consider a narrower range of tilt frequencies closer to 0 Hz, where tilt effects are most pronounced. This results in a different plot between the ``OBStools`` version and the MATLAB ``ATaCR`` version, but these differences should not affect the tilt noise removal process.

 OBStools is a package containing Python tools for processing broadband
 ocean-bottom seismic (OBS) data. Current functionalities include removing
-vertical component noise from tilt and compliance effects, and calculating
-compliance functions from vertical displacement and pressure data. The code uses 
+vertical component noise from tilt and compliance effects, calculating tilt orientation from three-component seismic data, and calculating compliance functions from vertical displacement and pressure data. The code uses 
 the ``StDb`` package for querying and building a station database and
 can be used through command-line scripts.
