MPES appdef hierarchy (also NAP-XPS)

[lukaspie]

From workshop:

• Do we want/need the separation of NXmpes/NXpeem?
• Where to place fixed energy kPEEM without energy resolution (Momentum microscope with hemisphere)?
• APXPS should have its own app def where we specify all relevant sensors/environments/data axes.
  • You would also like to store mass spec / GC data for operando experiments.

From Sandor:

• Are the required fields enough so that a data consumer could work with this set of data?
• AppDef separation shall be based on the different requirements of the expected data analysis tools
• do we need separate AppDefs for PEM? IPES?
• possible priority (also based on market share): XPS, ARPES, PEEM, liquidjet

Discussion:

• remove NXmpes
• have all sub app-defs one level below NXphotoemission
