The list of detector names in a run can be found from the unix command-line like this:
detnames exp=xpptut15:run=59 (print out names of standard detectors) detnames -e exp=xpptut15:run=59 (print out names of EPICS variables)
The same information can be obtained in a python script like /reg/g/psdm/tutorials/examplePython3/detNames.py:
from psana import *
ds = DataSource('exp=xpptut15:run=59:smd')
detNames = DetNames()
print('*** Detector Names (Full-Name, DAQ-Alias, User-Alias) ***')
for detname in DetNames():
print(detname)
epicsNames = DetNames('epics')
print('*** Some Epics Names (Full-Name, DAQ-Alias, User-Alias) ***')
for ename in epicsNames[:4]:
print(ename) # only print a few
In general, each detector can have 3 names. Only the first is guaranteed to exist for all detectors:
- a "full-name" defined by the DAQ which can be complex
- a "daq-alias" defined by the DAQ at the time when data is taken
- a "user-alias" defined by the user on a per-experiment basis (to be implemented)
