Maximum Likelihood Source Detection

After initial source detection, emldetect applies a maximum likelihood algorithm to refine the detected sources, offering improved positional accuracy and error estimates.

Key Command:

emldetect imagesets=MOS1_image_full.ds expimagesets=MOS1_expmap.ds \
    bkgimagesets=MOS1_bkg.ds boxlistset=eboxlist_map_1.ds ecf=2.0 eml_nmulsou=2 \
    mllistset=emllist_1.ds mlmin=10 determineerrors=yes

Output Files:

`emllist_1.ds`, `emllist_2.ds`, `emllist_pn.ds` (Source lists for MOS1, MOS2, PN)

This step refines the sources by calculating the likelihood of detection and estimates key properties, including source flux and errors.
