>		Standalone AMPEL installation requires considerable disk space. So it is advised to first develope your filters in the testing environment, and then deploy them to the production environment.

Clone the following repository:

https://github.com/AmpelProject/Ampel-contrib-sample

Read the documentation.

Test your fiters with a test dataset or a full night of ZTF alerts data.

Once satisfied with your results, the filters will be deployed in AMPEL.

To do that, fork the github repository, implement your changes there and notify AMPEL people.

Your filter will be integrated in the next AMPEL release and your stream will become operative.

When did the public survey start?

Added:
>
>		 March 20, 2018.
 

Where is the public data?

Added:
>
>		 Public alerts can be obtained from https://ztf.uw.edu/alerts/public/ or a variety of third-party services (e.g., http://mars.lco.global/).

Images, catalogs, and lightcurves will be released through IRSA after the first data release (in ~Q2 2019).

 

What are the data products?

Added:
>
>		 Alert packets from difference images, images, direct imaging catalogs, and source-matched lightcurves. These are the same as the products available for the collaboration surveys.
 

In what format is the data?

Added:

How do I know when a specific field will be observed?

Added:
>
>		Each night's observing plan is updated at the start of the night, and depends on which programs are active, past observing history (including weather), etc., so it is not possible to reliably predict nights in advance when or if a field will be observed.
