Data Products

The PTF project generates various data products. The raw and processed data products are immediately available to the project members only. The public data releases are documented here.

The LBL pipeline is designed primarily to identify transient candidates by using image differencing and automated artifact/real source classification. The PTF transient marshal ( offers the following products (only available to collaboration members).

1) Light curves, including additional follow-up photometry from other telescopes.

2) Follow-up spectroscopy. All information related to supernova discovered by PTF can also be found at

3) Forced photometry service: entails performing forced PSF-fit photometry on targets of interest on difference image products generated with PTFIDE. Typically used to generate publication-quality lightcurves.

Archival Products

The IPAC pipeline provides more data products which can be downloaded via the IPAC data archive. Currently, only a subset of these products are available to the general public; members of the collaboration have access to all products. The list of data products is follows:

1) Single frame reduced images (subset publicly available).

2) Source photometry (catalog files) extracted from the reduced images, based on PSF-fitting and aperture photometry. Calibration is tied to the SDSS system (Ofek et al. 2012).

3) Reference images (publicly available). These are co-adds of single-epoch exposures similar in size to the single reduced frames. Only a subset consisting of high-quality frames are used to generate these products for the archive. Custom produced coadded images can also be made according to specific frames and/or time-ranges for collaboration members.

4). Asteroids are identified during the real time processing and periodically submitted to the Minor Planet Center for achival (observatory code: I41).
