eShel settings for adjusting dispersion

Post by James Foster »

I'm on my 40th try to get the orientation and dispersion correct on my eShel2, but thought the experts here can get me a faster answer. Here is where I'm at now:

I've successfully completed the "Camera Rotation test", but can't proceed to the "ThAR test" until I get the circles in the above image aligned with their respective wavelengths:

6583.906
6677.282
4510.733

Otherwise I get the error message: "The number of columns is different than 1" or the error box below in French:

Is one of the settings responsible for rotating the ThAr either CW or CCW to get all three circles to match the corresponding calibration wavelengths shown above?
