A Lambda detector appears in online.xml like this:
<device> <name>lmbd</name> <type>DETECTOR</type> <module>lambda</module> <device>petra3/lambda/01</device> <control>tango</control> <hostname>haslambda01:10000</hostname> </device>
Note: This hostname, haslambda01, referes to one of the loan pool detectors.
Note: The detector name, lmbd, avoids any conflict with the wavelength.
