thresholdIsoph MultiframeDetector WSA Isophotal analysis threshold {catalogue extension keyword:  THRESHOL} real 4 counts -0.9999995e9 ??
Tunable parameter, the default is to set this to 1.5 skynoise as a compromise between detecting close to the limit of the data and not being swamped by spurious sources. It is possible to push the data limit fainter but at the expense of a large increase in spurious sources. LSBG detection requires a more subtle add-on to the catalogue and could be added given suitable demand.
