NUNEZ, Luis A; QUINONEZ, Fernando  e  SARMIENTO CANO, Christian Andrés. Data Provenance Validation for the LAGO stations Sierra Negra and Chacaltaya. Iteckne [online]. 2013, vol.10, n.1, pp.104-112. ISSN 1692-1798.

Some results on the search of Gamma Ray Burst from the LAGO Collaboration are presented. These are obtained after validating the quality (provenance) of the data recorded at two LAGO installation (Sierra Negra (Mexico) andChacaltaya Bolivia). We analyze the GPS marks at data collected. During this validation process we have found inconsistencies between the expected detection rate and the one recorded by the acquisition system. This was found at SierranNegra in 2008 and at Chacaltaya from 2006 to 2009. Then, we propose an strategy to perform the analysis of the data collected in order to recover those parts with optimum detection frequency. Next, we label them in ROOT-C++ format as Good Run Data List (GRDL). In order to perform a more correct data analysis at LAGO repositories, a GRDL recipe is provided. Finally, do a search for gamma-ray bursts on the validated data, by using the method of the excesses.
