dodal.devices.util.lookup_tables#

All the public methods in this module return a lookup table of some kind that converts the source value s to a target value t for different values of s.

Functions

`energy_distance_table`(lookup_table_path)	Returns a numpy formatted lookup table for required positions of an ID gap to provide emission at a given beam energy.
`linear_interpolation_lut`(filename)	Returns a callable that converts values by linear interpolation of lookup table values.

async dodal.devices.util.lookup_tables.energy_distance_table(lookup_table_path: str) → ndarray[source]#

Returns a numpy formatted lookup table for required positions of an ID gap to provide emission at a given beam energy.

Parameters:: lookup_table_path (str) – Path to lookup table
Returns:: Lookup table
Return type:: ndarray

dodal.devices.util.lookup_tables.linear_interpolation_lut(filename: str) → Callable[[float], float][source]#

Returns a callable that converts values by linear interpolation of lookup table values.

If the value falls outside the lookup table then the closest value will be used.

Parameters:: filename (str)
Return type:: Callable[[float], float]
