We present the public release of the first complete catalogues of Frontier Fields Abell-2744 and MACSJ-0416 cluster and parallel pointings.
The catalogues include multi-band photometry (8 HST bands, deep Ks from the HAWK-I FF program, and Spitzer-IRAC 3.6 and 4.5 um), magnification, photometric redshifts and rest-frame properties, plus a variety of diagnostic information. The cluster pointings have been analysed following a multi-step procedure to remove foreground emission from intra-cluster light and very bright galaxies. Photometry from low-resolution IR bands has been derived with T-PHOT.
Two papers describing in details the catalogues and the procedures followed to obtain them have been submitted to Astronomy and Astrophysics and are available on the arXiv:
The full catalogues can be downloaded from this link http://www.astrodeep.eu/frontier-fields-download/ .
The table below gives links to the original fits images. They have been combined to create the HiPS that can be viewed in Aladin.
"N/A" in the table means that the corresponding fits image is not available.

The table below gives links to the processed fits images. Processed images are the result of the procedure to subtract foreground light from ICL and bright cluster galaxies, as described in Merlin et al. 2016. They are displayed on a different scale with respect to the original images, to make faint sources more evident.
For parallel fields, the processed images are the same as the original images, but with different scale levels to see fainter sources. The original images for parallel fields are in the table above.

ID: Identication number in the input photometric catalogues. The IDs are organized as follows:
RA, DEC: Positions of objects.
MAG_…: AB magnitudes.
MAGERR_…: Relatives uncertainties for each magnitude.
ZBEST: Corresponds to the reference (median) photo-z value except when a match with a publicly available high-quality spectroscopic source is found within 1 arcsec. Sources for which the photo-z run did not converge to a solution are set to ZBEST=-1.0.
ZBEST_SIQR: Median photometric redshift uncertainty range (equal to 0 for spectroscopic sources).
MAGNIF: Median magnification (cluster fields), or magnification from the Merten model (parallel fields).
ZSPECFLAG: The value is set =1 for sources with spectroscopic redshift, =0 otherwise.
MSTAR: Stellar mass in units of 109M⊙ (assuming Salpeter IMF).
SFR: Star-formation rate in units of M⊙/yr.
RELFLAG: This flag is meant to provide a combined indication of the robustness of photometric and photo-z estimates.
It is possible to add your own catalogues on the image in Aladin Lite. To do this, you must first upload your catalogue, in VOTable format, to the storage space at the CDS site, using the link "Upload your catalogues".
The best is done to automatically detect the columns of the file that contain the coordinates. If the selected colums for RA and dec are not the correct ones, you can choose the correct columns manually before sending the file to Aladin Lite.
With the "View your catalogues" button, you get a list of all your saved files. Use the checkbox to display the file in Aladin Lite. The color that appears near the checkbox is the color in which the sources are displayed in Aladin Lite.
If an error occurs during the loading of the file, this is indicated. The main reason for errors is that the file is not in the correct VOTable format.
You do not need to register to be able to upload tables in your storage space, but we do recommend to register as:
