Data points for the curve of n_s-r contour diagram
When we use getdist to plot the contour diagram, we can get the curves. Does anybody know how to extract the data points of the curve? I want to use these points for some other purpose.
Actually, I want to get the experimental data points on ns-r diagram. Can anybody help me?
Thanks a lot!

Data points for the curve of n_s-r contour diagram
Thank you! Antony Lewis!
Yes, I use the following command
density=samples.get2DDensity('ns','r')
density.normalize()
But how can I output these into a txt file? And what is the structure or meaning of data in density? Sorry for my very poor knowledge in python. I will be very grateful if you can help me more!!

Re: Data points for the curve of n_s-r contour diagram
You can access x, y and P elements of Density2D directly, as set in the class constructor:

Or just call density(x,y) to get an interpolated table as your preferred values (Density2D inherits from RectBivariateSpline).

Thank you! Finally, I get the output data with 256*256 data points. But When I plotted them by myself, it seems to be very unsmooth, highly distorted? How can I get the similar figure as the getdistGUI displays? I mean, can I get exactly the data used in the getdistGUI curve?
Thanks!
Thanks!
