File to upload Uploaded file 'csv' (Amer. or Euro. style). •
Iff (above) no file is uploaded, then data such as the following default (below) are used.
Always expected: 'csv' format, with a header (discarded).
'csv' data Screen data (in 'csv' format),
ignored if a file (above) is uploaded
Rates Heating rates. •
Show values ? Shows the graph coordinates.

Computes pyrolysis kinetics by the Kissinger1 method from either: a) an uploaded 'csv' file; or (without the file) b) the 'csv' data inserted in the textarea. Thus, if (in 'a)') a file is uploaded, the data in the textarea are ignored.

The screen data (above) lead to Ea = 182.007E+03, A = 122.245E+12. Typical uploadable 'csv' files: file1 (giving 202.4E+03, 8.1E+15); file2, file3.

Draws plots of: the regression line, and the DTG curves.
