... and including the changes concerning ORGX= 3130 ORGY= 3040, MAXIMUM_NUMBER_OF_PROCESSORS=2
MAXIMUM_NUMBER_OF_JOBS=8, and TRUSTED_REGION=0.00 1.5 :
<pre>
JOB= XYCORR INIT COLSPOT IDXREF DEFPIX INTEGRATE CORRECT
MAXIMUM_NUMBER_OF_PROCESSORS=2
MAXIMUM_NUMBER_OF_JOBS=8
ORGX= 3130 ORGY= 3040  ! check these values with adxv !
DETECTOR_DISTANCE= 99.9954
OSCILLATION_RANGE= 0.500
X-RAY_WAVELENGTH=  0.6525486
NAME_TEMPLATE_OF_DATA_FRAMES=../../APS/19-ID/2vb1/p1lyso_e.0???.img
! REFERENCE_DATA_SET=xxx/XDS_ASCII.HKL ! e.g. to ensure consistent indexing 
DATA_RANGE=1 360
SPOT_RANGE=1 180
! BACKGROUND_RANGE=1 10 ! rather use defaults (first 5 degree of rotation)
SPACE_GROUP_NUMBER=0                  ! 0 if unknown
UNIT_CELL_CONSTANTS= 70 80 90 90 90 90 ! put correct values if known
INCLUDE_RESOLUTION_RANGE=50 0  ! after CORRECT, insert high resol limit; re-run CORRECT
FRIEDEL'S_LAW=FALSE    ! This acts only on the CORRECT step
! If the anom signal turns out to be, or is known to be, very low or absent,
! use FRIEDEL'S_LAW=TRUE instead (or comment out the line); re-run CORRECT
! remove the "!" in the following line:
! STRICT_ABSORPTION_CORRECTION=TRUE
! if the anomalous signal is strong: in that case, in CORRECT.LP the three
! "CHI^2-VALUE OF FIT OF CORRECTION FACTORS" values are significantly> 1, e.g. 1.5
!
! exclude (mask) untrusted areas of detector, e.g. beamstop shadow :
! UNTRUSTED_RECTANGLE= 1800 1950 2100 2150 ! x-min x-max y-min y-max ! repeat
! UNTRUSTED_ELLIPSE= 2034 2070 1850 2240 ! x-min x-max y-min y-max ! if needed
!
! parameters with changes wrt default values:
TRUSTED_REGION=0.00 1.5  ! partially use corners of detectors; 1.41421=full use
VALUE_RANGE_FOR_TRUSTED_DETECTOR_PIXELS=7000. 30000. ! often 8000 is ok
MINIMUM_ZETA=0.05        ! integrate close to the Lorentz zone; 0.15 is default
STRONG_PIXEL=6          ! COLSPOT: only use strong reflections (default is 3)
MINIMUM_NUMBER_OF_PIXELS_IN_A_SPOT=3 ! default of 6 is sometimes too high
REFINE(INTEGRATE)=CELL BEAM ORIENTATION ! AXIS DISTANCE
! parameters specifically for this detector and beamline:
DETECTOR= ADSC MINIMUM_VALID_PIXEL_VALUE= 1 OVERLOAD= 65000
NX= 6144 NY= 6144  QX= 0.051294  QY= 0.051294 ! to make CORRECT happy if frames are unavailable
DIRECTION_OF_DETECTOR_X-AXIS=1 0 0
DIRECTION_OF_DETECTOR_Y-AXIS=0 1 0
INCIDENT_BEAM_DIRECTION=0 0 1
ROTATION_AXIS=-1 0 0    ! at e.g. SERCAT ID-22 this needs to be -1 0 0
FRACTION_OF_POLARIZATION=0.98  ! better value is provided by beamline staff!
POLARIZATION_PLANE_NORMAL=0 1 0
