ZTF Update – QZ, Frank

Bad weather last week

Filter exchanger doing better now, but still being worked on.

Need to mask stars before machine learning scan for streaks.

Tom, Emily, and QZ screen streaking candidates and report interesting cases

ZMODE

Considering experimentation with four nights.

QZ warns that his tests a couple months ago decreased the signal to noise.

MSK: Downloading science images failing recently. Will contact Frank with more details.

Asteroids lightcurves – Rex

Working on machine learning of lightcurves via character recognition. Providing 2D binned images to computer science team for inspection.

Follow-up – Chow-Choong

Working on getting IAU code for smaller telescope at Lulin Observatory. (QZ and BB will help on this)

Bryce

Question about association between detections and objects

Frank: Using ASTChecker (includes comets). Written by Bill Gray and available online.

UW now has an alert stream copy.

Putting in ZTF follow up proposal for ARC 3.5-m, 2018Q3.

Comets – Mike

Looking to define a filter for picking up any solar system object. Inspected ZTF AVRO schema, and identified a set of interesting parameters.

How about a histogram of ssobj distance to alerts?

AOGS talk in Surveys and Spacecraft Missions to concentrate on comets. Will look at data, especially those of spacecraft targets to make more relevant for session.

Including ZTF as part of a NASA funding proposal.

Tom

Looking at nightly ID'ed streaks, considering how to make it more efficient.

George H is leading NASA NEOO proposal to work on solar system tagging in ZTF data.

Emily: help to screen streaking images
