7.3 Main menu “Data Editor”
7.3.1 Modify old .dat-files
Modifying existing dat-files:
1.
At first you will see two combo-boxes to choose a catalogue and a material.
2. Then click “open file”. Some new features become visible: either a list with cauchy coefficients or a table
with dispersion data
If you like to change these old data (=adding of constants or multiplying with a factor), just click on ADD
or MULTIPLY in the appropriate row. It is possible to change each cauchy coefficient separately, but not
a single value in a table. If you want to change table values, you have to do this with an external text
editor.
3.
After adding or multiplying click on “save dat-file” or click “reset modifications”
Then the software will automatically switch to the page “save dat-file”.
7.3.2 Save DAT-files
Be careful where you save this “new” material !
