Soft X-ray Harmonic Pressure Scan from Attosecond soft X-ray high harmonic generation

Harmonic signal as a function of photon energy and backing pressure used to generate figure 1 in the main text. Energy axis is in eV, pressure is in bar, signal is in counts at the detector.本数据集为用于生成正文中图1的谐波信号，其取值随光子能量(photon energy)与背压(backing pressure)变化。能量轴单位为电子伏特(eV)，压力单位为巴(bar)，信号以探测器处的计数为单位。
