“Hint-spec” attributed to SNRs as function of spectral results.
| Hint-spec | Criteria |
|---|---|
| 1 | At least three “low X/Fe” flags AND no “high X/Fe” flag |
| 1.5 | (Two “low X/Fe” flags OR low O/Fe) AND no “high X/Fe” flag |
| 2 | One “low X/Fe” flag (except O/Fe) AND ‘high X/Fe’ flag |
| 2.5 | Low Si/Fe AND no “high X/Fe” flag |
| 3 | ISM abundances, unfitted abundances |
| 3.5 | High Si/Fe AND no “low X/Fe” flag |
| 4 | One “high X/Fe” flag (except O/Fe) AND no “low X/Fe” flag |
| 4.5 | (Two “high X/Fe” flags OR high O/Fe) AND no “low X/Fe” flag |
| 5 | (At least three “high X/Fe” flags AND no “low X/Fe” flag) OR pulsar/PWN detected |
