## Updated Photometric redshifts with LePhare

The table *'minijpas.PhotoZLephare_updated'* contains photometric redshifts calculated with a custom version of LePhare (Arnouts & Ilbert 2011). This table supersedes *'minijpas.PhotoZLephare'* and solves several issues found in *'minijpas.PhotoZLephare'* after its public release (see below). The original table *'minijpas.PhotoZLephare'* remains available for reference, but we strongly advise to use the updated version.

Changes in *'minijpas.PhotoZLephare_updated'*:

- Solves bug in the implementation of the redshift prior caused PHOTOZ=0, Z_BEST68_LOW=0, and wrong Z_ML and PHOTOZ_ERR values in ~10% of sources. Redshifts, redshift errors and chi2 values are unchanged for unaffected sources.
- Solves bug in the interpolation of the PDF caused the cumulative_PDF to be miscalculated in sources with very narrow PDF. cumulative_PDF is now deprecated in favor of full resolution PDFs given in compressed form (sparse_PDF, see below).
- Statistical analysis of the PDFs showed that they overestimate the confidence of PHOTOZ for bright (r<19) sources and underestimate for faint (r>20) sources. A contrast-correction of the PDF now compensates for this effect.
- As a consequence of the contrast correction, the odds parameter now reflects the probability of a redshift error |∆z|<0.03 irrespective of the magnitude of the source.
- 'sparse_PDF' provides a compressed form (sparse basis representation) of the full resolution PDF (dz=0.002) after application of the contrast correction.
