PTF Objects List
Listed in IVOA Registry (Virtual Observatory)
Palomar Transient Factory (PTF) is a fully-automated, wide-field survey aimed at a systematic exploration of the optical transient sky.
Description
The PTF Objects catalog is a list of the targets that label each individual lightcurve with "collapsed-lightcurve" metrics. For objects with transient_flag = 0, the object is tied to a reference-image (coadd) detection.
If so, metadata characterizing the extracted reference-image source is also given. Such objects may be associated with time-variable sources that "survived" the co-addition process. For objects with transient_flag = 1, the object is transient at one or more epochs and would have been flagged as an outlier (hence omitted) during co-addition.

If so, no associated reference-image metadata exists, although collapsed-lightcurve metrics are still given.
