The TofNucleiZ check. |
| 145 |
|
|
<p> |
| 146 |
|
|
The routine selects events whose value of Zmean obtained from the ToF is in the range [Zmean - sigma*lowerBound, Zmean + sigma*upperBound]. Zmean and sigma are defined respectively as the mean and the standard deviation of the charge distributions obtained using ToFNuclei. The calibration values used in this routine (for all energies) are:<p> |
| 147 |
|
|
Z=1 | Zmean sigma ------------------------ S11 | 0.987 0.11 S12 | 0.988 0.12 S21 | 0.961 0.083 S22 | 0.966 0.10 S31 | 0.981 0.092 S32 | 0.979 0.095<p> |
| 148 |
|
|
Z=2 | Zmean sigma ------------------------ S11 | 1.96 0.12 S12 | 1.95 0.14 S21 | 1.95 0.13 S22 | 1.96 0.14 S31 | 1.99 0.14 S32 | 2.00 0.15<p> |
| 149 |
|
|
In current implementation, heavier nuclei up to oxygen are partially calibrated; means are taken equal to the particle's charge (Zmean = Z) and a single sigma is used for all ToF layers:<p> |
| 150 |
|
|
Z | sigma ----------- 3 | 0.20 4 | 0.25 5 | 0.32 6 | 0.40 7 | 0.45 8 | 0.50<p> |
| 151 |
|
|
The charge of the particle is detrmined by calling ToFNuclei::Get_Charge_ToF_std_layer(). First of all, the number of non-masked layers giving a valid charge information is checked to be greater than minLayers; then the bound on the charge value is checked for all valid planes. If at least one of the valid, non-masked planes gives a charge outside the bounds the routine will return <a class="el" href="TofNucleiZCut_8h.html#7cbf6ce6906f1524de86f3d84f23aa54ef9ad5021a1b83dd6a53eb225044d7c6" title="Discarded because charge is out of bounds in a layer.">TOFNUCLEIZ_OUTOFBOUNDS</a>. Note that this happens even if more than minLayers give a charge inside boundaries; for example, if minLayers = 5 and we have 6 good charge measurement of which only 5 are inside the boundaries, the check will fail. Notice that masking a layer has the net effect of reducing the number of layers: asking minLayers = 5 and masking two planes will result in return value of <a class="el" href="TofNucleiZCut_8h.html#7cbf6ce6906f1524de86f3d84f23aa54179c0935201f5d6ac6d7f00ebd1e959c" title="Discarded because charge can be measured in too few layers.">TOFNUCLEIZ_TOOFEWLAYERS</a> for all events, since the "effective ToF" has only 4 layers.<p> |
