# Input syntax as follows:
# <pre>
#            QE=<value>
#
#            %.\<key\>=\<value\>
#
#            PMT=\<module\> \<pmt\> \<PMT parameters\>
#
#            pmt=\<module\> \<pmt\> \<key\>=\<value\>[, \<key\>=\<value\>]
#
#            file=\<file name\>
#
# </pre>
# where 
#  - QE   refers to the global quantum efficiency;
#  - '\%'        to the default values;
#  - \<module\>  to the module identifier;
#  - \<pmt\>     to the readout channel;
#  - \<key\>     to one of the data members of the JDETECTOR::JPMTParameters data structure; and 
#  - \<value\>   to the corresponding value.
#
# The global QE is applied as a multiplicative factor to the default and PMT specific QEs.
#
# The default values are provided by the method getDefaultPMTParameters and
# can also be modified using method setDefaultPMTParameters.
# If no optional values are given, the default values are maintained.
#
# Finally, \<PMT parameters\> corresponds to the list of PMT parameter values that should
# be compatible with the I/O methods of the JDETECTOR::JPMTParameters data structure.
#
# Note that multiple input sequences should be seperated by a semicolumn ';' or be terminated by a newline.
# When multiple input sequences appear for the same target, the last sequence prevails.
