Radio observation in hydrogen line (1420MHz)

Determining the galactic rotation curve of the Milky successfully with my 1420MHz array

Galactic rotation curve from my data:

Below shows exercise of picking points for curve above in my data:

Compare my rotation curve above with typical Keplarian rotation curve (not from my data) – mine is clearly different – best explained by presence of dark matter:

My map of Milky Way based on my hydrogen 1420MHz observations so far:

Data set for all of above:
