    hello, can you please let me know to converte the data with five interval difference into a data with unit interval difference. thanks

      To convert your data from a five-interval difference to a unit interval difference, you could try plotting your data and then fitting it to interpolate the values at each unit interval. This way, you'll have a smoother dataset with the desired interval. Thanks

    Hi, Sir. I see that your reduced chi-square is far from 1, is it still acceptable for the fitting? (Im currently doing fitting for PL intensity curve, but my reduced chi-square also far from 1, but R^2 near to 1)

    • @SAYPhysics

      Thank you for your question! A reduced chi-square far from 1 suggests the model might not fully describe the data or uncertainties might be misestimated. However, if R² is close to 1 and the fit looks reasonable, it could still be acceptable, especially for qualitative analysis. It’s always good to ensure your uncertainties are accurate.

      To do fitting with a customized equation, I have another tutorial which will help you to understand. Thanks

    Hello sir, how can I fit BCS model equation of heat capacity

    • @SAYPhysics
      @SAYPhysics  2 หลายเดือนก่อน +1

      Thanks for your question! You can fit the BCS model equation for heat capacity in Origin by customizing the fitting function. If the BCS equation isn’t pre-defined in Origin, you can manually input it and perform the fit. I recommend watching my video on how to customize fitting equations in Origin for a step-by-step guide. It will help you set up the BCS model specifically. You can find the video at th-cam.com/video/ViIdEllu5pA/w-d-xo.html

      @@SAYPhysics I tried fitting it but it's gives me a value of 1.83E-295 for any value of X, my aim to fit C/T vs T^(2) and be able to obtain T_c from the BCS model fit.

      @mlungisimasondo3613 it's definitely not a valid value. Try refining your parameters. Thanks
