The lookup table

The lookup table has two folders:
(1)diffuse_tile_factor

   Column name naming rules: "slope" string prefixes and the value is slope;
   The range of slope is from 0 to 90.
(2)direct_tile_factor
   File naming convention: 
     "latitude_-55_slope_30.xlsx": "latitude_" string is latitude prefix, and the value "-55" is latitude; "slope_" string is slope prefix, and the value "30" is slope;
   Column name naming rules: "solar_dec_" string is prefix, and the value is solar declination;
   The range of solar declination is from -23 to 23.
   row name naming rules: aspect
   The range of aspects is from -1 to 360.

PLEASE NOTE:
(1)In order to make the look-up table more concise, the step length of latitude, slope, aspect, and solar declination are both 1 degree.
(2)Regarding the calculation method of the tilt factor, I have a python code, if necessary, you can contact me by email at [e-mail]
