== PALM error messages ==
'''Explanation'''\\
In the following list the error messages reported by PALM are mentioned. Each error message is identified unambiguously by a message identifier which is composed of two letters and a number. The second column contains the error message which is reported in the job protocol (see [../3.1]). In addition, the third column includes further explanations of the error.\\
