ZTF Exposures per Night

For PTF, we averaged about 200 exposures per night year round. Generally, the months with the worst weather also have longer nights, so the average stayed close to 200/night, although somewhat worse in April, May, and November (175),

PTF Slew Times Analysis

• PTF_HADEC_SLEW: Using PTF data from 2009 to 2017, this image shows DEC slew vs. HA slew. Times between exposures of 100s are shown as black pixels and 140s are white pixels. The dotted line is the 115s contour. The RA or Hour Angle (HA) slew and Dec slew are independent. So the time to reach the next target was usually the larger of each of these motions. (However, the DEC motion was slightly slower).

ZTF Exposures per Night

For PTF, we averaged about 200 exposures per night year round. Generally, the months with the worst weather also have longer nights, so the average stayed close to 200/night, although somewhat worse in April, May, and November (175), and somewhat better in September and October (220). We don't know yet the precise efficiency of ZTF, but assuming 30 second exposures and 10-20 seconds between exposures, would give us an average of 400-500 ZTF exposures per night at P48. (Possibly as many as 1000 exposures on the longest nights of the year.) See : PTF Operations Analyses .

PTF Slew Times Analysis

ZTF Operations (Discussion and Analysis)

PTF Slew Times Analysis

• PTF_HaDecAziSlew: This plot shows DEC, HA, and Azimuthal (dome rotation) slew in seconds. The straight line fits imply slew rates of 1.27, 1.67, and 4.69 degrees per second, respectively. The fits converge on approximately 27 seconds which represents settling and other overhead time. Except in rare cases, the azimuthal slew is not significant in the time delay between exposures. The HA data includes all exposures pairs with a DEC slew < 20 degrees, and the DEC data includes all exposure pairs with a HA slew < 20 degrees.
