String factor (snow)
1 with one string across the table, 0.75 with more
Unit –
What it is
The factor Townsend and Previtali 2023 added to the snow model: snow covering the lower modules of a table cuts the current of a string that runs along the bottom, so a table with one string across its width loses more than one with several.
Typical values and how to get it
1 when the table carries one string across its width, 0.75 when it carries more. If not given: 1.
