Notes. In Col. 1 are the source names in J2000 coordinates; Col. 2 notes the detection of the core at 6000 MHz; Col. 3 notes the detection of the extended emission at 6000 MHz; Cols. 4–6 are spectral indices of the total emission 
, 
and 
; Col. 7 says whether the SPC > 0.5 is present in the spectrum of remnant candidates between 150 and 6000 MHz; Col. 8 lists criteria used to confirm the source as a remnant in this work. The abbreviations used to represent the criteria in Col. 8 are explained in Sect. 7. Listed in Col. 9 is a flag where ‘1’ indicates that the source is confirmed a remnant, ‘0’ candidate is not a remnant. Mark ‘–’ stands for sources that were not observed in D-array at 6000 MHz and therefore denote the values that are missing.
