Bias introduced at different steps of the analyses.

	Fourier transform	Likelihood


QSO continuum	1.02	1.02
Spectrograph resolution	−	−
Noise in the data^a	0.98	1.00 to 1.13
Masking of sky lines	0.82 to 1.00	1.00

Notes.

^(a)

the noise-related bias was measured in the Fourier transform using the true continuum and is to be added to the other biases; for the likelihood, it includes systematic effects from all steps.
