## RedWare gf3 Commands Available


RadWare 软件 gf3 基本使用命令。

```text
| Commands | Means |
| :--- | :--- |
| AF [S]    |     自动寻找拟合光标两次点击的区域，S为灵敏因子，数值越大找到的峰越多，所以往小的设置建议1-4。拟合采用最小二乘拟合。 Auto-Fit: iteratively peak-find and peak-fit for a selected. region of the spectrum [with peak-find sensitivity S]    After the automatic fitting has completed, the program redraws the spectrum, and displays the limit, peak positions, and fit. It also lists the fitted parameters, areas and energies etc. on the screen. If you choose to do so, you are then free to modify the fit, by for example deleting or adding peaks (DP, AP), and/or fixing or freeing parameters (FX, FR, RW etc.), and then re-fitting with the modified setup using the FT command. | 
| NF      |       在光标两次点击的区域内手动用光标标志峰位置然后拟合 set-up a new fit for an arbitrary number of peaks (<16)  and do fit |
| FT [N]  |      N=1-15 : set-up for N peaks and do fit |
|         |     [N=0] : do fit using present parameter values 
|         |     N=-1 :  recalculate initial parameter estimates and do fit 。 It is equivalent to the pair of commands RF and FT. |
| AP      |      add a new peak to the fit set-up。 If you have a fit set up, but wish to add a peak to this fit, use the command AP. You will be prompted for the position of the new peak. The width of the new peak will be set to its initial starting value, so if the widths are free, but relative widths fixed, you will be given the option of reseting all non-fixed widths to their initial values also. If the new peak is not higher in energy than the previous last peak, you may also select to re-order the peaks in order of increasing energy. |
| DP [N]   |     删除拟合结果中编号为N的峰 delete a peak [peak no. N] from the fit set-up 。Use this command to delete a peak from a fit you have set up, if you wish to have fewer peaks. If you do not provide the number of the peak you want deleted, the program will prompt you for it. |
| WM [N]   |     change weighting mode (i.e. data error bars) |
|          |    N=1/2/3 : weight with   fit / data / another spectrum |
| RF       |     reset free parameters to their original estimates |
| FX [P]   |     fix additional parameters [par. P] or change fixed value(s) |
| FR [P,Q..] |   free additional parameters [pars. P,Q..] |
| RP N      |    free (N=1) or fix (N=0) relative peak positions to present values |
| RW N     |     free (N=1) or fix (N=0) relative widths |
| SW       |     change starting FWHM parameters, etc. |
| MA [N]   |     change limits for fit and/or peak positions |
|          |      [N=1-17 : change marker no. N] |
