TMS Software System
The current TMS
software system consists of a mixture of Python/Perl programs as well as several supporting infrastructure such as the LBT TCS
data dictionary subsystem for telemetry data support, and the Etalon software for sensor readout and management. So far, the procedures of TMS
correction only applies to one-sided LBC
. But eventually it will be able to handle binocular LBCs
as well as other instruments in the future. The Python/Perl programs are mainly used for high-level coordination and sensor data manipulation and transformation. They are the main parts of the TMS
software system. An overview of the software structure and the coordination and data transformation is given in a sketch shown below:
Kinematics analysis data sanity check criteria
The data we receive from the sensors are basically a vector of numbers. Each number is from a particular channel, and each channel is from a particular retro-reflector. To determine whether we can proceed to the kinematics analysis, we will need to check whether this vector of numbers we receive satisfy the following conditions:
- Each number is indeed a number (i.e., not a NaN value).
- Each number is not an outlier (e.g., within 1% of the reference value). Note: we are still finalizing the threshold on this check, and the definition of reference value is being defined as well. More precise definition will come soon...
- Each retro-reflector will have at least one channel data.
- A total of six channel data is required.
