============
config_instr
============
| The "config_instr" file defines parameters related to experiment and instrument used during the experiment, such as detector and diffractometer.
| The diffractometer and specfile are mandatory parameters for the 34-IDC beamline. The other parameters are obtained from the specfile. They can be overridden when included in this configuration file.

Parameters
==========
- diffractometer:
| Mandatory, name of diffractometer used in experiment.
| Must be defined for the beamline.
| example:
::

    diffractometer = "34idc"

- specfile:
| Optional (but mandatory for aps_34idc), specfile recorded when the experiment was conducted.
| example:
::

    specfile = "/path/to/specfile/Staff20.spec"

Parsed parameters
=================
| In a typical scenario at APS 34-idc beamline a spec file is generated during experiment and the parameters listed below are parsed from this file, so the user do not configure them. User may override the parameters.
- energy
| example:
::

    energy = 7.2

- delta:
| delta (degrees)
| example:
::

    delta = 30.1

- gamma:
| gamma (degrees)
| example:
::

    gamma = 14.0

- detdist:
| camera distance (mm)
| example:
::

    detdist = 500.0

- theta:
| angular step size
| example:
::

    theta = 0.1999946

- chi:
| example:
::

    chi = 90.0

- phi:
| example:
::

    phi = -5.0

- scanmot:
| example:
::

    scanmot = "th"

- scanmot_del:
| example:
::

    scanmot_del = 0.005

- detector:
| detector name
| example:
::

    detector = "34idcTIM2"
