Scans

The scans component tells Daiquiri how to interact with the scanning system. Currently only a Bliss handler is implemented

scans.yml

The scans.yml specifies the type and any parameters for that handler

Data Conversion

For 1d data (spectra) the zero and scale factor should be provided to allow conversion to units that daiquiri understands. zero is the zero offset of the data, and scale is the energy (eV) per bin

mca:
  conversion:
    zero: 0
    scale: 25

Bliss Handler

The Bliss handler should be told which session to connect to:

sources:
  - type: bliss
    session: test_session

The Bliss handler will watch this session and send events on scan start, new data, and end. This allows Daiquiri to follow scans interactively.

Blissdata Handler

In addition to the core bliss handler there is also a standalone blissdata handler. This handler does not require a bliss installation and should be directed to the blissdata redis_url:

sources:
  - type: blissdata
    session: test_session
    redis_url: redis://localhost:6379

Additional Handlers

Additional handlers can be implemented through the ScanSource interface.
