omdetect (omdetect-5.41) [xmmsas_20211130_0941-20.0.0]

CONFUSION FLAGS

These flags are set for "point" sources by omdetect when the photometry is performed. The flags are stored in an 8-bit integer variable and the settings are:

BIT NUMBER
REASON INTEGER VALUE
0 Point source has one or more sources within a radius of 6-12 unbinned pixels 1
1 Point source has one or more sources within a radius of 3-6 unbinned pixels 2

A source could have a confusion flag value of 3, indicating that both bits 0 and 1 are set.
