mfraclimit | no | real | 0.75 | ![]() |
Threshold value for MASKFRAC column. All sources with MASKFRAC![]() | ||||
brcolumn | no | string | RATE | |
Name of column to be used to define a circle of influence of a bright source (used to set flags 2 and 4)
| ||||
op1 | no | string | sqrt | sqrt|none |
Operation to apply to 'brcolumn' to build the total expression to calculate the radius of the circle of influence to set flag 2 (and 4).

fixext | no | real | 200. | ![]() |
Likely spurious extended sources flagged with flag 5 should be closer than this fixed distance to a brighter extended source.
| ||||
detmlfraction | no | real | 0.9 | ![]() |
Likely spurious extended sources flagged with flag 6 should have (for just
one of the 15 images) more than this fraction of the summed detection
likelihood
