'Alopeke and Zorro Sensitivity

You are here

Final results from the 'Alopeke and Zorro commissioning are still pending, but the speckle imaging sensitivity is expected to be similar to DSSI. Please see the DSSI Sensitivity web page for planning purposes.

Additionally, the following figure from Matson, Howell and Ciardi (2019), reproduced with permission of the authors, shows the 5-sigma detection limit curves for 'Alopeke.  Stellar companions with a separation and delta magnitude that fall below a given curve are detectable with speckle imaging. Note how the contrast for 'Alopeke is slightly better than DSSI, mostly given the improvement in the detectors. Zorro curves are expected to be very similar.
