Here you can download a public version of the data as a CSV file. Note that fields are separated by semi-columns, and not enclosed. First 3 rows are a header: timestamp, column names, column units.
Note that SNR coordinates are not always very precise, although they are sufficient to locate the object.
J2000_from indicates if the values given were obtained from:
Note that the column
size_coarse is only meant to provide an easy-to-use estimate of the SNR extension.
If the flag
size_imprecise is set, this indicates that such a coarse value is not an accurate representation of the actual morphology of the remnant.
More details are provided in the text fields
size_[radio|X], obtained commonly from radio observations and sometimes from X-ray observations.
All high energy observations are listed here (be they actual detections or not, and physically related to the SNR or not), separated roughly into four energy domains (around the keV, MeV, GeV, and TeV).
