This document contains a table with data on cross-sectional measurements of a roadway, including station locations, left (L), center (CL), and right (R) measurements of the road width, and elevation levels. The table includes station locations from 0+000 to 0+400 meters in 20 meter increments, with width measurements for each location and benchmark (BM) and point (PT) locations noted.

1. The document contains a table of station (STA), angle, correction, and log sine values.
2. Angles are adjusted in two steps using correction values to calculate adjusted degrees, minutes, and seconds.
3. Log sine values are calculated and compared at each adjustment step to check calculations.
