0 = no DNL correction
1 = Correction value (typically 0.31)
Parameter 1005 Start of DAq Data for DAn (Start Coordinate)
Parameter 1006
Start of DAn Data (Start Coordinate)
This pointer value defines the position in the coordinate list where the DAn coordinates begin, i.e. it
should equal the number of hardware coordinates.
If you want to analyze the data from the first hit you can set this value also to -1 and the program will
automatically enter the right number.
Parameter 1007 Hit number to be analyzed. Usually the position coordinates are calculated from the first hit in the
TDC channels (default value: 1). If you instead want to get position and time sum coordinates calculated
for a different hit number you have to enter the hit value here. Note that it can happen that the values
from different channels do not necessarily correspond to the desired particle hit number if reflections on
the raw amplifier signals or missed signals produce “false” hits in a certain TDC channel.
Parameter 1010 Time to Position calibration factor for PosX coordinate (v
⊥
in mm/ns)
DLD40: 1.32, DLD80: 1.02, DLD120: 0.77
For Hexanode (u): HEX80: 0.737, HEX120: 0.583
Parameter 1011 Time to Position calibration factor for PosX coordinate (v
⊥
in mm/ns)
DLD40: 1.43, DLD80: 1.13, DLD120: 0.82
For Hexanode (v): HEX80: 0.706, HEX120: 0.567
These two parameters define the value of position to time calibration, the effective signal propagation
speed across the delay-line. It depends on the size and geometry of the delay-line used. The suggested
values are only accurate within few percent for a given delay-line. If a higher precision is needed one needs
to make a position calibration with a test mask in front of the detector. If the detector image boundary
has an oval shape, exchange the values for X and Y (only for DLD) and try again sorting the data (may be
the physical dimensions of the anode have been exchanged during mounting).
Parameter 1012 Time to Position calibration factor for the w-layer (Hexanode only):
HEX80: 0.684
HEX120: 0.540
Please note that it is required to calibrate the numbers for parameters 1010-1012 for your anode more accurately. Please contact
Parameters 1013 to 1019 can be used for defining bin sizes of spectra (see spectra definition commands below)

Parameter 1020
Rotation offset center for coordinate PosX
Parameter 1021 Rotation offset center for coordinate PosY
These parameters define the center point for an online detector image rotation and also the center point
in the X/Y plane for a coordinate transformation into R/Phi representation. Note that R/Phi
transformation will only give good results if the position unit is mm (see parameter 1000).
Parameter 1022 Rotation angle in mathematical direction (counter clock wise) for an online detector image rotation (value
to be supplied in RAD or DEG depending on parameter 1003)
Parameter 1023 X-value of center for r/phi coordinate computation
Parameter 1024 Y-value of center for r/phi coordinate computation
Parameter 1025 MCP channel number. If the trigger signal is NOT the MCP signal the parameter 1025 shall contain the
channel number of the MCP signal to achieve sum spectra with the time reference set to the MCP signal.
Parameters 1026 to 1032 can be used to change the assignment of the “raw” DAQ coordinates from TDC
channels to the calculated (DAN) coordinates x1, x2, ...
Parameter 1026 channel number for x1
