Description |
Data Structures used at COR level. |
JMXi-DETE-MOD |
Contains the description of the JEM-Xi detector plane.
Values indicate active and inactive pixels, bad anodes and their
neighbours, calibration spectra overflow areas and permanent hotspots
if there are any |
Data Structures needed for Energy Correction |
See more details in Section and
Tables - . |
JMXi-CALB-MOD |
Lists the corrected upper limits of the bins used to convert
the
original 4096 energy channels into 256 calibration telemetry channels.
This table is used to bin the calibration data only since this is binned in the
DFEE and transmitted as housekeeping.
The bin boundaries have been corrected for any ADC non-linearity that might
arise
during flight. |
JMXi-FULB-MOD |
Lists the corrected upper limits of the bins used to
convert
the original 4096
energy channels into 256 full imaging and spectral timing energy telemetry
channels. The bin boundaries are corrected for ADC non-linearity. |
JMXi-RESB-MOD |
Lists the corrected upper limits of the bins used to convert
the original 4096
energy channels into 8 restricted imaging telemetry channels The bin boundaries
are corrected for ADC non-linearity. |
JMXi-SPCB-MOD |
Lists the corrected upper limits of the bins used
to convert the original 4096
energy channels into 64 spectral mode telemetry channels The bin boundaries
are corrected for ADC non-linearity. |
JMXi-SPAG-MOD |
Contains the fractional corrections in percent to the raw event energy
gain coefficients for all event modes from the JEM-Xi instrument as determined
by pre-flight calibrations and in-flight data. For each pixel the difference
is determined compared to the average gain of the entire detector area.
The second slice of this table contains the percent corrections to be applied
for each anode due to anode deaths and instabilities.
See also Section |
JMXi-FBDS-MOD |
Lists the nominal energy boundaries of the PI channels for
energy measurements obtained with full and spectral-timing modes.
This data structure is also used as the EBOUNDS extension of the redistribution
matrix file (RMF).
See more details in Section and Table . |
JMXi-RBDS-MOD |
Lists the nominal energy boundaries of the PI channels
for energy measurements obtained with restricted imaging mode.
See more details in Section and Table . |
JMXi-SBDS-MOD |
Lists the nominal energy boundaries of the PI channels for
spectra
obtained in spectrum mode.
See more details in Section and Table . |
Data Structure used for position correction
(see section ) |
JMXi-CORX-MOD |
Contains the corrected X positions in mm
from the center of detector for
Full and Restricted Imaging event modes from the JEM-Xi instrument.
It is a 2D table with axes along X and Y positions where the raw
values are used.
See more details in Section . |
JMXi-CORY-MOD |
The same as JMXi-CORX-MOD but for Y positions |
JMXi-PLLX-MOD |
Gives the X value (mm) of the lower left corner of the pixel |
JMXi-PLLY-MOD |
Gives the Y value (mm) of the lower left corner of the pixel |
JMXi-PSIZ-MOD |
Gives size of each pixel (cm
) |
JMXi-PRED-MOD |
Is the pixel redistribution description from the raw
pixels
on a regular pixel grid |
Data Structures used for Dead Time derivation |
JMXi-DEAD-MOD |
Contains the dead time model for the read time
for different events for both 8MHz and 16 MHz operation of the
on-board CPU. TRIGGERS lists the event counter ID number from the
on-board software and DEAD8_1 and DEAD16_1 give the time in seconds
to do the read in. The usual on-board CPU speed is 16 MHz. Also
contains a keyword for the double trigger effect.

Data Structures used for background handling |
JMXi-DBKG-MOD |
Contains maps giving the spatial distribution of background
counts at a number of energy levels including information about detector
areas that should nopt be used. |
Data Structure used for imaging and source finding |
JMXi-COLL-MOD |
Contains a collimator description in the form of two lists
of the coordinates of the collimator lamellae intersections.
X- and Y-coordinates of intersection at the top and at
the bottom are given in columns XSECTBOT, YSECTBOT, XSECTTOP, and YSECTTOP. |
JMXi-MASK-MOD |
Contains the mask description of JEM-Xi.
It is 2D table with axes along Mask X- and Y -axes. |
JMXi-OPNC-MOD |
Gives the coordinates (mm) of the centers of the open holes in the mask |
JMXi-VIGN-MOD |
Contains an array with vignetting factors for the
JEM-Xi instrument.
It is a 2D table with axes along X and Y-axes. This has been used to correct
source intensities for collimator shadowing but is now obsolete. |
JMXi-IROS-MOD |
Contains some basic parameters for the component: j_ima_iros |
Data Structure used for spectral analysis |
JMXi-ENRG-MOD |
Contains the table of ENERG_LO (lower limit of channel in
keV)
and ENERG_HI (upper limit of channel in keV) to be used
in conjunction with E_MIN
and E_MAX as found in JMXi-FBDS-MOD, JMXi-RBDS-MOD or JMXi-SBDS-MOD for the
spectral response matrix. |
