This folder contains the script called `create_sql_queries_for_experimental_data` that can be used to import experimental data into a MySQL database.
The script uses an input card containing the basic information about the measurement to be inserted and the experimental data itself.
It produces a set of MySQL queries that act on `laboratory`, `collaboration`, `experiment`, `observable_kinematic` and `observable_result` tables of the database `partons`.
For the three first tables, it is checked if the new data do not double the existing entries (in the case of repetition, the existing entries are used).
The script was written for and has been tested under GNU Awk 4.1.3.
Structure of the input card
---------------------------
The input card should follow the following structure (check `CLAS_ALU_asymmetries.dat` for an example):
1) provide measurement information (keep information in quotation marks where indicated):
```
LABORATORY "name"
COLLABORATION "name"
EXPERIMENT "year" "process" "type" "reference"
```
2) provide experimental points (as many as you want):
```
bin_index xB t Q2 Ebeam phi observable_name value stat- stat+ sys- sys+ err_tot
```
If you want to use single quotation marks, you must escape it, _e.g._ `"e\' + p\' + gamma"` instead of `"e' + p' + gamma"`.
