Some common definitions of 26ID scan detector channels
| Detector Channel number | EPICS Process variable | Description |
| D01 | 26idsclr1:scaler1.S1 | I0 - Integrated Ion chamber current after NES slits (change current amplification via yellow SR570 tab on main beamline screen) |
| D02 | 26idcXMAP:mca5.R1 | Bi - Fluorescence channel from outboard detector, summed ROI#1 - find and modify with MCA software from User Tools tab on main beamline screen |
| D03 | 26idcXMAP:mca5.R2 | Ti - Fluorescence channel from outboard detector, summed ROI#2 - find and modify with MCA software from User Tools tab on main beamline screen |
| D04 | 26idcXMAP:mca5.R5 | Fe - Fluorescence channel from outboard detector, summed ROI#5 - find and modify with MCA software from User Tools tab on main beamline screen |
| D05 | 26id:ccd.R01.Average | Integrated Intensity/Num Pixels for CCD ROI#1 - ROI#1 defines the total active chip area to be saved, so this is the total CCD intensity per pixel |
| D06 | 26id:ccd.R02.Average | Integrated Intensity/Num Pixels for CCD ROI#2 - usually tightly defined around the outgoing beam - Contrast here is related to diffracting volume |
| D07 | 26id:ccd.R02.XCentroid | X center of mass of intensity in CCD ROI#2 - This is related to lattice strain and rotation in the diffraction plane, scales away from center of ROI2 with signal/dark current |
| D08 | 26id:ccd.R02.YCentroid | Y center of mass of intensity in CCD ROI#2 - This is related to lattice rotation out of the diffraction plane, scales away from center of ROI2 with signal/dark current |
| D09 | 26idcDET:userCalc3.VAL | R02.Average - R03.Average, Background subtracted average intensity - ROI#3 typically set around an unused area, this is useful for viewing scans in progress with low contrast |
| D10 | 26idcDET:userCalc6.VAL | CCD Image number - If you are using the CCD DO NOT MODIFY THIS CHANNEL - Necessary for Matlab analysis routines |
| D10 | 26idctsrc:DMM1:Ch1_raw.VAL | Channel 1 - C Hutch digital multimeter - FOMX temperature |
| D11 | 26idctsrc:DMM1:Ch2_raw.VAL | Channel 2 - C Hutch digital multimeter - FOMY temperature |
| D12 | 26idctsrc:DMM1:Ch3_raw.VAL | Channel 3 - C Hutch digital multimeter - FOMZ temperature |
| D13 | 26idctsrc:DMM1:Ch4_raw.VAL | Channel 4 - C Hutch digital multimeter - SAMX temperature |
| D14 | 26idctsrc:DMM1:Ch5_raw.VAL | Channel 5 - C Hutch digital multimeter - SAMY temperature |
| D15 | 26idctsrc:DMM1:Ch6_raw.VAL | Channel 6 - C Hutch digital multimeter - SAMZ temperature |
| D16 | 26idctsrc:DMM1:Ch7_raw.VAL | Channel 7 - C Hutch digital multimeter - SAM Theta temperature |
| D18 | 26idpvc:userStringCalc3.VAL | Time of day - Units are fractional hours (ie 22.5 = 10:30pm) - use min and max of a linear scan to accurately estimate 2D scanning times, discontinuity in this channel indicates a hung scan |
