PTF-2 serves as a trigger for UV missions, offering 4.5x - 6x enhanced FOV compared to PTF. It can maintain nightly cadence in dark conditions with high throughput in U band. Enhanced detectability allows for early detection and reaction to Supernovae, with PTF-2 significantly improving detection capabilities, especially for young SNe. The yearly core-collapse SN number could double with PTF-2, with 50% detectable during dark time. Target numbers predict around 150 SNe per year, with expedited discovery rates post-explosion.

PTF-2 as trigger for UV mission FOV increase: x4.5 – x6 with respect to PTF. Can maintain nightly cadence during dark time (and dark parts of grey nights) on current PTF footprint
QEs STA-ITL CCDs can offer very high (>70%) throughput in U while still decent all the way to R. Substantial improvement (unique capability).
Detectability PTF can detect SNe on day 1 and react. PTF-2 will be much better. Young SNe (at least) are easier to detect in U (x5 – x10 more flux).
We know the PTF core-collapse yearly SN number, which is ~150. Given larger area (but denser sampling) of PTF-2, the yearly number would be ~300, of which 50% during dark time (U-band survey), so 150 a year, again. Given weather, about 50% should be discovered within a day of explosion, and ~10% within hours of explosion. Target numbers
