1.The dataset is the spectrum acquired by using 0.4/0.6-m long SHF.

2.There are 51 different pressure states from 0 MPa to 5 MPa.

3.For each pressure state, more than 130 spectra are collected.

4.In each spectrum, the value of the first row should be deleted. 

5.The first col of each spectrum is the wavelength, and the second col is the intensity.

6.The size of each spectrum is (508, 1)
