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: In this section we demonstrate that it is difficult to match the suggested braking law with the value of maximum rotational velocity of solar mass stars in open clusters of different age . We used data on rotations of stars in four clusters ( instead of the two used by Ivanova & Taam 2003 ) . Furthermore , we assumed a much more realistic initial rotation rate , close to the fastest rotating ZAMS stars and the initial angular momentum from protostars as discusses by Tinker et al . ( 2002 ) . In addition we adopted more recent estimate for the age of the Pleiades of 130 Myrs ( Stauffer et al . 1998 , Martin et al . 1998 ) .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
