KiDS DR5 file types and formats

Data product types

The following types of data products are provided for each individual tile:

• ugri Coadds: photometrically and astrometrically calibrated, stacked images; 1 per filter per tile; note: used for photometric measurements in multi-band catalog
• ugri Weights: weight frames (1 for each ugri1i2 Coadd)
• Flag images: FITS images with pixel flags in areas affected by bright stars (saturated pixels, diffraction spikes, etc.) (1 for each ugri1i2 Coadd)
• Source lists: lists of sources detected in single ugri1i2 Coadds
• r Detection images: photometrically and astrometrically calibrated, stacked r-band images from lensing-optimized pipeline; note: used for source detection for multi-band catalog
• r Detection weight images: weight frames (1 for each r Detection image)
• 10-band masks: FITS images with pixel flags combining the masks in all 10 bands present in the multi-band catalog

This corresponds to a total of 19114 files and a total data volume of 17 TB.

The multi-band source catalog covers all 1006 tiles, where overlaps between tiles are excised (contrary to the data products listed above), thus making this a single catalog with unique sources. Through the ESO catalog query interface the multi-band catalog can be queried as a single entity. However, for direct download the data are stored in multiple files: a metadata file describing the catalog contents and one (trimmed) catalog data file per tile. The total number of files in which the catalog is stored is therefore 1007 with a total size of 28.5 GB; the catalog contains 100,350,873 sources.

Naming convention

The naming convention used for all data products is the following:
KiDS_DR5.0_R.R_D.D_F_TTT.fits,
where R.R and D.D are the RA and DEC of the tile center in degrees (J2000.0) with 1 decimal place, F is the filter (u, g, r, i or i2), and TTT is the data product type. The value of TTT for the different data products is given in column 4 of the table below.

For example: the r-band stacked image of the tile "KIDS_140.0_0.5" is called KiDS_DR5.0_140.0_0.5_r_sci.fits and the catalog data file of the same tile KiDS_DR5.0_140.0_0.5_ugriZYJHKs_cat.fits.

The following table lists the types of data products provided in this release, together with descriptions of the file types and naming conventions used.

Image data format

The final calibrated, coadded images have a uniform pixel scale of 0.2 arcsec. The pixel units are fluxes relative to the flux corresponding to magnitude = 0. This means that the effective zeropoint is equal to 0 and the magnitude m corresponding to a pixel value f is:

m = -2.5 log₁₀ f.

The gain varies slightly over the field-of-view because of the zeropoint offsets applied to individual CCDs to homogenize the photometry. An average effective gain is provided in the FITS header of each image.

Subsequent photometric zeropoint corrections were derived from the catalogues and recorded in the image headers using the DMAG keyword. The keywords CALSTARS and CALMINAP give the number of Gaia stars that were used in the calibration, and CALMINAP is the value of the GAaP MINAPER parameter (0.7 or 1.0) that was used for the photometry that resulted in this zeropoint.

The r-band detection images, which result from a reduction using THELI, specifically designed for optimal image shape measurement and small astrometric reductions, are the basis of the multi-band catalogue. They have a pixel scale that is closer to the native OmegaCAM pixel size of 0.213".
