Output Files

  1. PPS product (to be read by task srcmatch): EPIC emldetect source list
  2. Optionally: source maps (one output image per input image)


Table 2: Columns of the output source table

ID_INST instrument ID; 1: PN, 2: MOS1, 3: MOS2; 0: summary row
ID_BAND energy band number (band number 0: summary band)
ID_CLUSTER cluster id; sources fit simultaneously have same number
SCTS source counts
SCTS_ERR source counts error
X_IMA source image pixel X coordinate
X_IMA_ERR error of image pixel X coordinate
Y_IMA source image pixel Y coordinate
