NN provider

Nucleon-nucleon offline database. Low energy experimental data. J.E. Amaro, R. Navarro-Perez, and E. Ruiz-Arriola/ Instituto Carlos I de Fisica Teorica y Computacional, andDepartamento de Fisica Atomica, Molecular y Nuclear.Universidad de Granada, Spain. / Build databaseOnly the first time you run this app or in the case of an update. Search database and write data into fileChoose the channel, observable, and energy range. Click start. Check thebox if you wish to write the results in a file located in the/nnprovider/ folder of your SD-card. Output formatThe user of this app can choose different options for showing the outputdata Separate dataSeparate data can be ordered by energy or by group of data. Each datumis stored in a single line in the provided output file. The meaning ofthe columns is the following:channel,nlink,observable,energy,angle,value,error,omega,normalization,key,star. Group data. Order by energySeparate data in groups ordered by energy and observable. The datawithin a group differ in angle only. The heading of each group providesthe following information:energy, number of data in the group, normalization error, zero, zero,zero, channel, observable, keyEach datum within the group consist in:angle, value, error, omega. Group data. Order by groupSeparate data in groups ordered by experiment. The heading of each groupspreads over several lines with the following information:link to nn-online.org, reference, channel, number of data, normalizationerror, plus several lines of additional information.Each datum within the group is shown in a separate line with thefollowing information:Energy, angle, observable, value, error, omega Include star (*) dataIf checked, the data marked with a star(*) in the nn-online database aredisplayed. Otherwise they are ignored. Include excluded dataIf checked, the data excluded from the restricted database aredisplayed. Otherwise they are ignored. Android content providerNNprovider is also a database that you can use as a content provider foryour smartphone or tablet. A content provider is a data base sharedwithin your Android device. If you have programming skills you can writean Android app for searching this database, using the following URI:| Uri uri= Uri.parse("content://es.ugr.amaro.nnprovider/tabla"); |To performing a search within the content provide you use:|Cursor cursor=getContentResolver().query(uri, projection, selection, selectionArgs, sortOrder);|This cursor is a Java object containing the data as follows:|String id =cursor.getString(0);String channel =cursor.getString(1);String observable =cursor.getString(2);String normalization=cursor.getString(3);float energy =cursor.getFloat(4);String angle =cursor.getString(5);String omega =cursor.getString(6);String value =cursor.getString(7);String error =cursor.getString(8);String key= cursor.getString(9);String reference =cursor.getString(10);String star =cursor.getString(11);String url =cursor.getString(12);String relative =cursor.getString(13);String more =cursor.getString(14);String excluded =cursor.getString(15);String absolute =cursor.getString(16);String ndatos =cursor.getString(17);String nlink =cursor.getString(18); | InfoWork supported by Spanish DGI (grant FIS2011-24149) and by Junta deAndalucia (grant FQM225).
