Japanese term or phrase: 2倍の値を平均とし
The following passage is part of a paper on data assimilation in the molding simulation of composite materials.

What does '2倍の値' refer to in this context?

図3の真値モデルに対して複合材料積層板の上面と下面の10点，合計20点の温度を観測値として取得し，式(14)に基づき，積層板の上下面に定義している熱伝達率で空気と積層板との熱伝達率h(air)，ヒータと積層板との熱伝達率h(heat)をEnKFにより推定した．

なおアンサンブルメンバーは，真値の熱伝達率h(air)，h(heat)に2倍の値を平均とし，h(air)，h(heat)の分散を持つ正規分布乱数を加え50個用意した．

データ同化に関するパラメータは表2を用いるが，時間ステップは4 s，wtは0 W/kgで推定を行っている．

English translation:twice the value of xxx is used as the average value
Explanation:
Without getting into the details, the literal translation would be something like "twice the value of xxx is used as the average value." "xxx" may be either "h(heat)" or "the true value of heat transfer coefficient h (air) and h (heat)." (Sorry, if my answer is off-topic.)
