1. Kay Graf Timecalibration Meeting Vidyo, 12/03/2015 Database and Calibration

2. Storage of Calibration Data in the Database ●See: http://www.wiki.km3net.de/index.php/Database/Product_Tests_and_P arameters http://www.wiki.km3net.de/index.php/Database/Product_Tests_and_P arameters ●distinction: ● "data streams“ vs. ● "data sets of unique values to be applied for a finite timespan (e.g. structures/objects)“. ●for calibration: mostly second needed ●fits into the already defined „TEST/CALIBRATION/MONITORING“ ●needed information: ● parameters to store (name, SI unit, range, needed accuracy) ● associated products (if any) ● validity span of parameters/update rate (e.g. measured once per year or once per second) ● what are the parameters necessary for (online calibration, offline calibration, information storage) 2

3. ●Product data+calibration tests description ● Basic entity: the «parameter» ● Name ● Type ● Allowed values ● Array/Scalar ● Array dependency ● Basic entity: the «test/calibration/monitoring» (includes factory datasheets) ● Name ● Description ● PBS/Variant of eligible products ● List of parameters ● Parameter list: links a test to the parameters THE KM3NET DATABASE A. Albert, C. Bozza – Valencia, Feb 2015 PRODUCT TESTING AND INFO From: Valencia Coll. Meeting:

4. ●Product data+calibration tests documentation ● Testing operation ● What ● Where ● When ● Who ● How ● OK/FAIL ● Parameter values ● Linked to the «parameter list» ● Linked to the «testing operation» ● NOTICE: Always use International System units (e.g., not mA but A) – can be defined THE KM3NET DATABASE A. Albert, C. Bozza – Valencia, Feb 2015 PRODUCT TESTING AND INFO

5. ●Product data+calibration tests documentation ● Internal test results ● ASCII format for manual upload ● XML/JSON format for automatic upload, see: http://www.wiki.km3net.de/index.php/Database/XML_Data_Service http://www.wiki.km3net.de/index.php/Database/XML_Data_Service ● Automatically generated from test definition ● Upload by cURL / wget or other webclients ● Used for DarkBox/GreenBox THE KM3NET DATABASE A. Albert, C. Bozza – Valencia, Feb 2015 PRODUCT TESTING AND INFO

6. ●Product data+calibration tests retrieval ● GUI interface representation ● Automatically generated from parameter definition ● Plots ● Formerly automatically generated ● Now switching to plot definition tables in the DB ● Plot definition retrieval OK ● Javascript/SVG plots OK ● Need some sample data to complete/develop HTML interface ● Programmatic representation ● XML/JSON format identical to the one used for upload ● Direct retrieval of test results for specific UPI ● Use by cURL/wget or other web clients: see http://www.wiki.km3net.de/index.php/Database/XML_Data_Service http://www.wiki.km3net.de/index.php/Database/XML_Data_Service THE KM3NET DATABASE A. Albert, C. Bozza – Valencia, Feb 2015 PRODUCT TESTING AND INFO

7. What needs to be done ●Timecalibration (Mieke’s tables) are in place ● Need to establish the writing/reading ●Other calibration is also partly done - an example (use case) would be needed for everything to be stored ● Definition document is there (but that is not so helpful if you want to implement something) ● C&S group can help but not do the job 7
