SECTOR requires in STEP 1 to select, download and open an XLS template. As shown in Table 1, the user can choose among a set of templates according to the number of seasons (max. 3) and patches (max. 100). The file “Templates.XLS” in the SECTOR folder comprises hyperlinks to the respective XLS files (see Table). This selection procedure has been introduced for convenient use of the resulting files and their outputs by the user. The principle calculations, however, are identical in all templates, so there will be impacts on the results as such.
