The folder sensitivityOffsetAdps contains the additive continuum offsets and the sensitivity (encoded as 1-sigma in 1 hour) for point and extended-source calibrated spectra, for high (HR) and low (LR) spectral resolution.
The sensitivity plots, for HR only, point source calibration on the left, extended source calibration on the right:
