Odd Radio Circles and Their Environment
Round 1
Reviewer 1 Report
A few comments. Very small number of sources but very interesting sources. I am a bit concerned about ignoring two of the sources by declaring "they are different" essentially when in fact they may not actually be. Can't these two also be included in the analysis? The analysis centers around whether there is an overdense environment around the host galaxies and surely these "sources/source" could be included in that discussion? The analysis can be done with them and without them. That would strengthen the paper.Author Response

Reviewer 2 Report
The paper shows five Odd Radio Circles (ORCs) from deep radio surveys, and studies the environment of the ORCs. They find that three single ORCs either lie in a significant overdensity or have a close companion. The result may indicate that the environment is important in creating the ORC phenomenon, which will be helpful for further investigating the properties/origin of the ORCs.
Line 27, remove ‘dot’ before [1].
Line 32, ‘there is’ a galaxy?
Line 43, ‘there are’ three?
Line 46, ‘C is at’...
Line 49, ‘spiral galaxy at C’.
In the caption of Fig.2, for the Right-side image, the contours in green, red etc are not described correctly.
In the caption of Fig.3, the position of putative host galaxy between A/B should be also circled in red. It may be better to show a contour map than the grey map.
Line 50, ‘it is the galaxy’?
Line 68, ‘DESI (full description)’...
Line 74, ‘the projected spatial distribution’?
Line 82-84, the meaning of ‘tangential distribution’ should be explained, also for ‘a tangential separation’ in Line 88.
Line 87, line 91, the coordinates should be used following a standard IAU format.
In References, check the format is correct, e.g. in lines 186, 216, etc.
