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: An important diagnostic , strongly confirming the low pair dominance independently of the pair equilibrium calculations , is the absence of an annihilation feature in the observed spectrum . Purely thermal plasmas do not show distinct pair annihilation lines even if dominated by pairs ( Zdziarski 1986;Stern et al . 1995 ; . However , the data for this source rule out purely thermal plasmas , see Figure 1 . On the other hand , hybrid plasmas can emit X - ray spectra well reproduced by Comptonization on mostly thermal electrons , but still exhibit relatively narrow annihilation features . The absence of such a feature in the average spectrum therefore implies the pair abundance to be very low .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
