About how to draw two dashed lines over an anisotropic superconducting gap

[fimoto1990]

Dear all,

I have a question about how to draw "guided lines to the eyes" over an anisotropic superconducting gap as shown in Figure 4 [https://docs.epw-code.org/doc/MgB2.html].

I was wondering if someone could give me a tip for this kind of plotting.

Best regards,

Fumihiro Imoto

Dear Fumihiro,

To draw "guided lines to the eyes" over an anisotropic superconducting gap as shown in Figure 4, we take an average over the minimum and maximum gap distributions in the lower and upper gap regions at each temperature. Then join the points.

There is also another way to fit the anisotropic gap distributions, such as BCS curve fitting generally applicable to low-Tc superconductors.

regards,

Check out this formula:

You can fit the average of the gap over the full temperature range, and use that to interpolate
