You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: The comparison of the expected spectra of light nuclei with the recent **data** of KASCADE-Grande and ARGO appears very problematic: while individually both sets of **data** can be fitted with reasonable values of the SN parameters and CR acceleration efficiencies, there is no model that can fit both at the same time. KASCADE-Grande **data** require a SN energy ESN = 2 × 10 51 erg, an efficiency ξCR = 20% and a rate of explosion of ℜ = 1/110 yr −1 that lead to a maximum energy EM ∼ = 3.7 PeV, whereas we can fit ARGO **data** with ESN = 10 51 erg, ℜ = 1/15 yr −1 and ξCR ∼ = 5.2% that lead to EM ∼ = 507 TeV. The disagreement between these two experiments is a purely experimental problem, that requires a serious and careful assessment of the systematic uncertainties involved in the adopted experimental techniques.
