重建相关器方法已用于以拟合独立的方式研究介子相关函数中的热效应。这项技术最近已扩展到重子扇区。在这项工作中，不同的方式来实现这种方法的重子粒子的检查。利用真实的和合成的数据，发现对于重子，如Xi_{cc}（ccu）重子，不同的选择是等价的，而对于较轻的核子，不同的实现方式的影响是最小的。与使用FASTSUM Generation 2L热集成的所谓“双比“的进一步比较表明，重建相关器比和双比包含几乎相同的定量信息。
Reconstructed-correlator methods have been used to investigate thermal effects in mesonic correlation functions in a fit-independent manner. This technique has recently been extended to the baryonic sector. In this work different ways of implementing this approach for baryon correlators are examined. Using both real and synthetic data it is found that for heavy baryons, such as the $Xi_{cc}(ccu)$ baryon, different choices are equivalent and that for the lighter nucleon the effect of different implementations is minimal. Further comparison to the so-called"double ratio"using the FASTSUM Generation 2L thermal ensembles shows that reconstructed-correlator ratios and double ratios contain nearly identical quantitative information.
