Properties files

The class Properties provides the parsing of simple properties files.

Definition of a property

A simple property can be defined by:

key: value

or with a unit (the CLHEP system of units is used):

key: value * unit

Also available as a unit is the "%" sign.

Definition of a properties table

You can think of many properties which have to be supplied as a function of a certain variable. For this, a table can be defined. The header reads:

table-name: tabular
   field1   field2   field3   ....
Or again with units::
table-name: tabular
field1 / unit field2 / unit field3 / unit ...

whereas the columns should be separated by tabulators to increased readability. Additionally, the properties could be edited with a spreadsheet software when importing / exporting as CSV file.

Example

For SiPMs, the photon detection efficiency is a function of the photon wavelength:

photonDetectionEfficiency: tabular
   entry wavelength / nm   efficiency / %
