Ask for Input: Are They Real Signals or Copy-Paste
Recently, we found some abnormal infrared spectra reported in biochar researches. Parts of these spectra have similar (or nearly the same) but small signals (please find the examples below). If they are real signals from the samples, what were their origin? The studies did not give any explanation about it. Or if they are noises, do these similar/same noises suggest copy-past from one to the other? The 5GH welcome input at 5GH@5gh.org.cn
