... A source list compiled by either emldetect or eboxdetect can be added to the RGS source list. ... These EPIC source lists include positions and count rates for each source within several different energy bands. ... The values of the LABEL column of the RGS source list must be unique. For EPIC sources this is partially achieved by including the value of the EPIC source list column ML_ID_SRC or BOX_ID_SRC in the label for that source. ... Note that all LABEL values are converted to upper case. ...
