 4) Once you have identified the brackets that should be used for calibration, edit the l1l2.config file and specify the brackets by listing the .pav files as shown in the example (note that you need to give the full path to the .pav files if they are not in the same directory). The parameters in the top part of the file are relevant for the Monte-Carlo simulations used to estimate uncertainties. A mandatory parameter to edit here is the estimate for the limb-darkening coefficient of your star (set to 0 if you want a UD fit). \\ 4) Once you have identified the brackets that should be used for calibration, edit the l1l2.config file and specify the brackets by listing the .pav files as shown in the example (note that you need to give the full path to the .pav files if they are not in the same directory).

-6) Pressing RUN MC will start the Monte-Carlo simulations to calculate uncertainties of the UD fit to the data. The simulations include uncertainties in wavelength scale, calibrator diameters, measurement errors, limb-darkening coefficient and correlations between wavelength channels (see {{:chara:files:l1_l2.jpg?linkonly|here]] for an example output screenshot). This feature is so far only implemented for a simple UD fit. \\+6) Pressing RUN MC will start the Monte-Carlo simulations to calculate uncertainties of the UD fit to the data.

 Note: /exp is default in this program as I've found it to improve the calibration in almost all cases. Note: /exp is default in this program as I've found it to improve the calibration in almost all cases.
