Here is a high-level summary of the ZTF survey parameters for reference. Some parameters are estimates and will be improved as our simulation effort continues.

Basic Parameters

Camera field of view: 47 deg^2

Line: 20 to 22

MSIP Survey parameters

Added:

>
>

These are the MSIP surveys specified by Shri for the initial 1-1.5 years of the survey.

Celestial Cinematography/Northern Sky Survey

Added:

>
>

This is a three-night cadence survey of the Northern Sky.

The survey footprint will be a large fraction of the visible sky, irrespective of Galactic latitude. The Northern boundary will be Dec +90. The southern boundary will set the survey extent and is TBD; it may vary slightly by season. Reasonable ranges may be ~15-30 degrees S. We expect to be able to survey somewhere between 15k-20k square degrees over three nights.

Each night a field is visited, take one g and one r exposure separated by at least 40 minutes.

Galactic Plane Survey

Added:

>
>

The footprint for the Galactic Plane Survey is the strip of fields within +/- 6 degrees of b=0 (and North of ~Dec -25 or so, TBD). Whenever a field in this footprint is up (e.g., above airmass 2 for > 1 hour), observe it every night, once in g and once in r separated by at least 40 minutes.

Weather and Observing Time

Added:

>
>

With weather losses, the average total P48 observing time throughout the year is about 5.75 hours per night, with only modest seasonal variations--the longer winter nights are balanced by poorer weather.

Detailed weather data is available in the survey simulator; see here
