1) Many papers on the same theme do not describe their radiotelescopes into
sufficient detail nor they provide extensive results of their measurements.
Therefore we are only citing [3] and [4] that are both comparable to our
instrument, both are well documented and both are available free on the web.
We believe that we did better than the two cited references but we prefer
to leave the final decision to the reader.

2) Making a single plot takes more than 12 hours. During this time we have
to lucky enough not to pick any radio interference like cellular phones, WiFi
or spark ignition and to have the Sun far away from our antenna beam.
Further we have problems with our antenna. In December 2016 the elevation
drive developed problems related to lubrication. The manufacturer did not
want to provide us any advice. We solved the lubrication problem in April
2017, however the position of the Sun was unfavourable to make measurements
in the galactic plane. Therefore we made some rather succesful measurements
on pulsars using a completely different receiver to be published in a
separate paper. The severe thunderstorm on June 25th, 2017 broke trees,
flipped road signs and chimneys and destroyed our antenna and positioner.
We estimate that it will take several months to rebuild our radiotelescope. 

3) Larger antennas used by the professional astronomers only provide better
angular resoulution of the hydrogen clouds. An excellent comparison is
already published in [4] and following articles of the same group.
