21cm band. Refurbishing the dish with a new Cantenna.

Recommended Posts

Hi ZiHao,

I think I've found one error.  It was the r = r +/- delta_r bit and obviously for QII & QIII there is only one solution which is the r = r + delta_r one.  I still have quite a lot of further non-standard points.  Here's a cleaned up version:


I'm tempted to download the LAB stuff and see what happens if I chart that.

Thanks for your help.

I feel I've got as far as I can go here.  I've suppressed some of the worst invalid numbers.  So here is my plot with its asymptote at 180 degrees (I don't know what I can really do about that) compared with the same plot for LAB values on the right.

Now I think I'll spend some time thinking about rotation curves.

Thanks for reading this far and thanks @Victor Boesen and @ZiHao for your support and help.

Kind regards
