simple 1-D scan using EPICS synApps sscan record
assumes the sscan record has already been setup properly for a scan
PARAMETERS
sscan : Device
one EPICS sscan record (instance of `apstools.synApps_ophyd.sscanRecord`)
running_stream : str or `None`
(default: ``"primary"``)
Name of document stream to write positioners and detectors data
made available while the sscan is running. This is typically
the scan data, row by row.
If set to `None`, this stream will not be written.
final_array_stream : str or `None`
(default: ``None``)
Name of document stream to write positioners and detectors data
posted *after* the sscan has ended.
If set to `None`, this stream will not be written.
device_settings_stream : str or `None`
(default: ``"settings"``)
Name of document stream to write *settings* of the sscan device.
This is all the information returned by ``sscan.read()``.
If set to `None`, this stream will not be written.
poll_delay_s : float
(default: 0.001 seconds)
How long to sleep during each polling loop while collecting
interim data values and waiting for sscan to complete.
Must be a number between zero and 0.1 seconds.
phase_timeout_s : float
(default: 60 seconds)
How long to wait after last update of the ``sscan.FAZE``.
When scanning, we expect the scan phase to update regularly
as positioners move and detectors are triggered. If the scan
hangs for some reason, this is a way to end the plan early.
To cancel this feature, set it to ``None``.
NOTE about the document stream names
Make certain the names for the document streams are different from
each other. If you make them all the same (such as ``primary``),
you will have difficulty when reading your data later on.
*Don't cross the streams!*

Scan plan for the multi-sample grid scan.
This function takes in a templated excel spreadsheet and constructs a
spatial scan plan. Single-shot with total exposure specified in
the ``Exposure time`` columns will be executed at the spatial
points specified in the ``X-position`` and ``Y-position`` columns.
A set of optional arguments ``crossed``, ``dx`` and ``dy`` can be
passed so that 4 extra data will be collected with respect at each
spatial point. An optional wait time between spatial points data can
also be set to avoid residuals (ghost image). Please see
``Examples`` below.
Parameters
----------
dets : list
A list of detectors will be triggered in the experiment.
Note the first three detectors in the list must be in the order
as "area detector, x-motor, y-motor".
exp_spreadsheet_fn : str
filename of the spreadsheet contains sample metadata in each
well, locations, exposure times and all additional metadata.
This spread MUST be placed inside ``xpdUser/Import``.
crossed : bool, optional
option if to perform a crossed scan in each well. If it's true,
then at each well (x0, y0), 4 additional data will be collected
at (x0-dx, y0), (x0+dx, y0), (x0, dy+y0), (x0, y0-dy). Default
to False.
dx : float, optional
offset in x-direction for crossed scan per well. Must be
a float if ``crossed`` is set to True. Default to None.
dy : float, optional
offset in y-direction for crossed scan per well. Must be
a float if ``crossed`` is set to True. Default to None.
wait_time : float, optional
Wait time between each count, default is 5s
Examples
--------

# plan. The first 3 detectors should be in the sequence of
# "area_det, x-motor, y-motor" used in the scan.

# Note, this spreadsheet MUST be placed in the ``Import`` directory

Notes
-----
1. ``gridScan_sample`` used in the example is in fact an empty
dictionary (and it has been defined in this script as well).
Sample metadata is handled inside the plan, therefore it's
simply an auxiliary object.
2. ``gridScan`` yields a generator so you would need to construct
it every time after using it. As demonstrated in the Example,
we redefine the ``grid_plan`` again after printing the summary.
Similarly, if you wish to execute the same scan plan, you would
have to repeat the syntax.
