Radio observation in hydrogen line (1420MHz)

Comparing Ptarmigan and 21cm Plate Yagi data at LRO, collected over few days 26-31/8/2024 – processing both data sets in ezRA

I used ezRA software suite to process the data set presented in the post:

https://www.astronomy.me.uk/comparing-pharmigan-and-21cm-plate-yagi-data-at-lro-collected-over-few-days-26-31-8-2024

Both aerials pointed 163 degrees Azimuth at LRO.

Ptarmigan Array = 77 degrees elevation.

Plate Yagi = 73.5 degrees elevation.

It appears to me that far more detail of galactic structure coming out in the Plat Yagi plot compared to the Ptarmigan Array plot. However, I have sort advice (see link above) on whether this is, in fact, the case.
