Evaluating Machine Learning Models for Supernova Gravitational Wave Signal Classification

This dataset contains gravitational wave (GW) data used in our research work Abylkairov et al. (2024). The first 10,000 columns represent the gravitational wave strain D · h [cm] for the corresponding time values ranging from -993 ms to 6.9 ms, with a step size of 0.1 ms. The zero time refers to the time of core bounce. Each row within these first 10,000 columns corresponds to 864 different gravitational wave signals.

Columns 10,001 to 10,005 contain the following additional parameters:

T/|W|: The rotational parameter.

GR_or_GREP: Binary indicator for the signal type, where 0 denotes GR and 1 denotes GREP.

EOS: The equation of state (EOS) model, where 0 corresponds to SFHo, 1 to LS220, 2 to HSDD2, and 3 to GShenFSU2.1.

f_peak: The peak frequency [Hz].

D Delta h: D · ∆h [cm].

For each row (representing a single gravitational wave signal), these parameters provide information about the signal's rotational parameter, type (GR or GREP), EOS model, peak frequency, and D · ∆h.

Note: In the f_peak calculation procedure, we truncated the GW signal at 4.5 ms after the end of the core bounce (see Richers et al. (2017) for details).

本数据集包含Abylkairov等人2024年的研究工作中所使用的引力波（gravitational wave, GW）数据。其前10000列对应时间范围为-993 ms至6.9 ms的引力波应变D·h [cm]，采样步长为0.1 ms。其中零时刻指代内核反弹时刻。该前10000列中的每一行对应864个不同的引力波信号。

第10001至10005列包含以下附加参数：
T/|W|：转动参数。
GR_or_GREP：信号类型二元指示符，其中0代表广义相对论（General Relativity, GR），1代表GREP。
EOS：物态方程（equation of state, EOS）模型，其中0对应SFHo，1对应LS220，2对应HSDD2，3对应GShenFSU2.1。
f_peak：峰值频率，单位为Hz。
DΔh：D·Δh [cm]。

对于每一行（代表单个引力波信号），上述参数可提供该信号的转动参数、信号类型（GR或GREP）、物态方程模型、峰值频率以及D·Δh的相关信息。

备注：在f_peak的计算流程中，我们将引力波信号截断至内核反弹结束后的4.5 ms处，详细细节可参见Richers等人2017年的研究。
