From TORTORA to MegaTORTORA—Results and Prospects of Search for Fast Optical Transients
Figure 9
Different modes of operation of MegaTORTORA system. Left: wide-field monitoring mode in a white light. Middle: insertion of color and polarization filters as a first step of follow-up routine upon detection of a transient. Right: repointing of all unit objectives towards the transient. In the latter regime of operation the system collects three-color transient photometry for three polarization plane orientations (illustrated by a different stroke directions in figure) simultaneously. Mode transition speed depends on exact hardware parameters (objective and CCD weight, motors used, etc.), but is expected to be less than 0.3 seconds.
