Fig. 2.


Characteristic transmission of the RTF for the 36 slices that define the OTELO survey spectral scan (red solid lines), as dictated by Eq. (5). The thick solid line corresponds to the synthesis of OTELO RTF responses (hereafter OTELO-custom) a kind of intermediate-band (∼230 Å) filter affected by the telescope, the OSIRIS camera, and the QE of the detectors. Note the location of those responses, avoiding the Meinel bands represented by the airglow spectrum (thin black line) from Hanuschik (2003). The green line represents the transmission (scaled to the total efficiency of the system) of the order sorter OS 911/42 used to acquire RTF data.
