1- Data scans where direct beam was blocked by Terra Lab where generated with:
C:\model\Tools\Shade\Generate_filenames.bat
using as input:
set input_file=C:\Version2\Palmer\Vol15\Data_products\PAL_v15.2_DB3_meas.csv
set parameter_file=TerraLab.csv

2- Resulting file is: Direct_beam_blocked_PAL_V15.csv

NOTE: Generate_filenames.bat does not take into account whether or not the sun is visible. 
Scans measured during overcast sky are not more affected by Terra Lab than scans
during clear sky when the direct beam is not obstructed by Terra Lab. 
Data were maually inspected, also using Version 0 data time series in ACCESS. 
The file Direct_beam_blocked_CS.txt includes manually screened scans. These scans are
clear sky scans affected by Terra Lab.
