XUNDL Overview Libby McCutchan National Nuclear Data Center Brookhaven National Laboratory, NY USA
XUNDL FY17 statistics Compiled 710 datasets from 310 papers Center Papers Datasets McMaster 137.5 275 TUNL 38 60 ORNL 11.5 15 MSU 60 130 LBNL 18 34 BNL 31 67 ANL 13 115 International* 5 14 Full database is 7605 datasets for 2542 nuclides * Most of international contributions from Trieste WS split 50/50 with McMaster
XUNDL FY18 statistics Compiled 585 datasets from 253 papers Center Papers Datasets PRC Pre-Pub McMaster 86 293 10 papers TUNL 32 42 ORNL 3 3 MSU 54 101 3 papers LBNL 17 22 BNL 46 73 16 papers ANL 15 51 Full database is 8087 datasets for 2634 nuclides (as of October 29, 2018)
XUNDL Developments Prior compilation workflow Related image Image result for physical review c cover Paper is compiled, checking codes run Scan of all journals Publication Communicate with authors Resolve issues Request additional data Archive communications
XUNDL Developments A more efficient workflow Paper is compiled, checking codes run Communicate with authors Resolve issues Request additional data Paper is submitted to journal Image result for physical review c cover Publication Image result for referee clipart To referee
XUNDL Developments March 2018 pilot project started with PRC You opt-in to have data sent to NNDC for checking This is NOT an extra referee step We have tools to help you (and we would do it anyway) Thank you to Chris Wesselborg and Rick Casten We hope this is start to increased dialog between researchers and data program
Pros Substantial improvements to published data No need for lengthy comments in compilation No need to archive author s communications Published data matches data in database Additional data going into the databases Several cases where we encouraged use of Supplemental Material and they listened ! Serious errors are being identified And some unexpected benefits By checking references, we recently identified an entire conference proceedings missing in NSR and ENSDF.
Most important Pro We are increasing the dialog between researchers and data community Feedback is overwhelmingly positive
Cons 1 week time limit for return Need to have compiler available at all times Checking and reports are in general more detailed than the correspondence we have with authors Additional time is spent on compiling But sometimes this leads to a pro i.e. Identifying missing conference proceeding Correction of fission yield measurements
The Future We continue with PRC project They will soon move from opt-in to opt-out McCutchan, Singh, Chen cover the articles New NNDC staff will be trained (K. Auranen compiled 2 papers in first week) Future discussions will be needed How long do we wait to see if article published ? How do we contact authors for unpublished data ? How (when) do we incorporate that data into XUNDL ?
The Future In discussion with Elsevier to implement in their publishing process Majority of opt-out give reason of data evaluator as a co-author. A second pair of eyes never hurts. Please send us your compilation and we will do a double check.
