Help on Interpreting the Search Result

The results of a successful search are initially displayed as a short summary of each record listed roughly in reverse chronological order (i.e. most recent first). 20 records are displayed per page with the option to move on to the next 20, go to the previous 20 or jump to the last 20.

The summary comprises:
  • The first author (linked to the full record display)
  • The experiment lab. number and name (linked to the INSPIRE Experiments database)
  • Information on the publication references
  • The paper title
  • A link to the full data record
  • A link to list only the table headers in the record
  • A link to the INSPIRE record for this publication
Selecting the "Full data record" link (or the "author" link) will display the complete Reaction Database entry for that publication.

[Selecting the "Short data record" will display only the data table headers for that publication from which there are links to the complete data entry for individual tables.]

In the full data record, after initial data comments and information about overall systematic errors (if available), are the data tables themselves roughly corresponding to the data tables and figures in the papers (indicated in brackets).

The format of the tables is primarily for visual inspection and the other output options after the 'Table' number allow other output possibilities:
Input format used to enter new records into the database (ideal format for new submissions)
plain text
As it says, without the html additions
Output in AIDA (xml) format
Output in PyROOT format
Output in YODA format
Output in ROOT CINT format
Output in matplotlib format
Output in DataMelt format
Output in MARCXML format
Output in YAML format (native format for new hepdata.net site)
There are additional links at the bottom of the "y" columns:
Display a single plot of that set of data. This takes you to another display in which, as well as the plot, various other information is shown as well as options to replot the data changing the type of axes (linear/logarithmic). You can also add this plot to the selected list for later plotting with the 'add this plot to list' button.
Selects that dataset for later plotting with data from this or any other dataset in the database.
Making Composite Plots

One of the new features of the new Reaction Database is the ability to combine data from any record into one composite plot, thus allowing easy visual comparisons. As mentioned above, this is accomplished using the "SelectPlot" link on the full record display or the "add this plot to list" link on the Plot display. Doing either of these will take you to the "current list of selected plots" page which has options to display the combined plot as well as to manipulate the datasets by removing them from the list. The summary link will display more information on the individual dataset. Again there are various options to alter the axes types. Other links allow easy movement back and forward to the datasets and plotting page. The list of current selected plots is specific to a user/session and remains active for the complete user session, which generally means until the browser is exited.
