Macros
The macros can be written in .mac file and compiled by qdo in SPEC.
Example: qdo /usr/local/lib/spec.d/macros/pilatus1M.mac
Syntax:
def <command> '{
<motor> <position>;
}
Existing macros:
- takahashi in/out
- sample in/out
- dada_ on/off - gives additional information after ct command
- eiger<on> / off / slow(single image) / scan(linescan) - switch before scans or meshes
Components
- Takahashi - beam cleaning pinhole of 50 um
Data organization for dmesh
Every line of the scan is saved in a separate .h5 file
