This directory contains ancillary data products.                              
These ancillary data products are CSV files with one line containing column   
headers. Each CSV file contains one or more vector (Cartesian spacecraft      
coordinates) and scalar values. The vectors represent things like the center  
of the field of view of the sensor. The scalars represent things like the     
half angle of the conical aperture of the low energy end of the LEMMS sensor. 
Each vector or scalar value has its own line in the CSV file. The first       
column in the line is a description of the value. In the case of vectors, the 
next three columns are the X, Y and Z values respectively. In the case of a   
scalar values the second column is simply the value. For the sake of easy     
parsing lines containing scalar values are padded to four columns. The        
geometry data for CHEMS and INCA are constant, but, the geometry data for     
LEMMS contains a variable representing the turn table position.
