Whether to remove peaks

When I run the code, I find an error indicated. It happens to all the dataRay example codes, including this one, do you know what's the reason?
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

There is generally a lack of documentation for using individual modules (e.g. WinCamD, Stage, Fitting)

There should be documentation on how to launch the software from say Windows Explorer

Modify the fitter class such that the correlation and covariance matrix is also returned together with the sd_beta

If a command is running and Ctrl+C is sent, it seems to cause some form of communication error

ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it

Currently the z_R may only be found in one direction (i.e. the beam can only come in through the dial end of the stage)

Should implement and test some way so that the stage can also be rotated.

Both dll were in the same folder, the NanoScanLibrary.dll was found.

If one starts Measure.take_measurements(), there are no safe ways to stop the operation.

• How to save to specific file
• How to read from file for plotting

If there is astigmatism and the center of the x and y axis are different, the code does not take that into account.

Nanoscan unable to change the scanning speed

Should document functions like .rmove, .move

We should check if the software used is compatible with GPL, or perhaps another license like MIT might work better

Currently, the setup:

1. Finds the center
2. Finds the Z_R
3. Measures the M^2

The M^2 measurement may be sped up by

1. Taking rough measurements of the beam caustic
2. Doing a fit to obtain rough Z_R and center measurements
3. Taking a few more measurements within the +/-Z_R range.
4. Doing a refit

This reduces the total number of measurement points significantly.

Possibly split off NanoScan and WinCamD into separate repos and package them as packages (py-nanoscan) and (py-wincam) for example.

Currently the Rayleigh Length for each axes is found independently. If the bounds for the Y-Axis can be adjusted during the finding on the X-Axis, then it should converge faster on the results.

The code does not offer a GUI for its users.

For CLI app, it might be good to add a prompt to ask where to save the file

The repository should be packaged into a python package for easy installation
