- Table 1:
Number of candidate members of NGC 6530 for each selection method.
Panel 1a: stars in the ACIS field; diagonal terms are the total numbers
of stars for each method, while off-diagonal terms are those found by
two methods simultaneously. Panel 1b: the same representation
for the entire WFI field, including the ACIS field (X-ray sources
are not reported as there is no additional X-ray information outside the
ACIS field). Panels 2a and b: members found exclusively by one
method, in the ACIS and WFI fields. Panels 3a and b: members found by
any of the Q indices, regardless of X-ray detection, including X-ray
sources and excluding them, respectively, in the ACIS and WFI fields.
