  1. PPS product (to be used by tasks esplinemap and emldetect) : EPIC eboxdetect source list

Description of source list columns:

Column name Unit Description
BOX_ID_SRC   Source index
ID_INST   Instrument (1:EPN, 2: MOS1, 3: MOS2)
ID_BAND   Index of input images per instrument, =0 for summary row
SCTS cts Net source counts corrected for PSF losses
SCTS_ERR cts Statistical error of SCTS
BOX_CTS cts Raw counts in detection box without background subtraction or PSF corrections.
X_IMA image pix X source position in image pixels
X_IMA_ERR image pix Statistical error of X_IMA
Y_IMA image pix Y source position in image pixels
Y_IMA_ERR image pix Statistical error of Y_IMA
LIKE$^*$   Detection likelihood
BG_MAP cts/pix Background counts at source position
BG_RAW cts/pix Mean counts/pixel in background area, without correction for scattered source counts. For map mode identical with BG_MAP.
EXP_MAP seconds Exposure at source position.
FLUX erg/(cm$^2$ sec) Flux calculated from RATE and parameter ecf
FLUX_ERR erg/(cm$^2$ sec) Statistical error of FLUX
RATE cts/sec Count rate (SCTS / EXP_MAP)
RATE_ERR cts/sec Error of RATE
RA deg Right ascension
DEC deg Declination
RADEC_ERR deg Statistical error of RA and DEC
LII deg Galactic longitude
BII deg Galactic latitude
HR1   Hardness ratio as defined via parameter hrdef
HR1_ERR   Statistical error of HR1
HR2   Hardness ratio as defined via parameter hrdef
HR2_ERR   Statistical error of HR2
HR3   Hardness ratio as defined via parameter hrdef
HR3_ERR   Statistical error of HR3
BOX_SIZE pixel Size of detect cell in image pixels
EEF   Enboxed energy fraction in detect cell. Calculated from the medium accuracy CAL PSF. Set to 1.0 for rebinned images.
DIST_NN arcsec Distance to nearest neighbour.

$^*$ Note that column LIKE was named SIGMA in eboxdetect versions up to 4.8. The content of LIKE is identical to that of SIGMA in these older versions.
