stacks made with the y-(i.MP9702) filter. The y stacks are listed in Tables 31 and quoted in Tables 15 and 16. All Deep fields comprise both i and y-band stacks, but the i stacks contain much more images and are much deeper. The two input-ldac and output-ldac catalogues as well as the chi2-RSC catalogue contain the 75 parameters described in Table 28 to 30. However, they do not have the same input nor the same of output parameter values. Some of them are vectors, so the number of entries are also not the same and can be much higher than 75. In particular, they do not have the same detection threshold, or the same number of MAG_APER aperture magnitudes. Columns of catalogues with both the ’.cat’ or the ’.ldac’ extensions are defined in the ’.param’ files. For the Wide survey, there are 77 columns in the .ldac catalogues, 181 columns in the chi2-RSC, 24 (resp 30) in the merged MAG_AUTO (resp MAG_SNLS) M-SC catalogues, 536 in the merged MAM-SC catalogues and 827 in the patch-merged catalogues WPM-SC. All images have a new magnitude ZP set to 30 AB magnitudes. The magnitudes of objects in the final stacks are computed as follows: m = 30 − 2.5 log(counts) . (19) It is important to realise that the .cat catalogues are produced using specific selection criteria or filters selected by TERAPIX from past experience and after discussions with experienced users and the CFHTLS Steering Group. They are certainly not suitable for all scientific goals. Please examine the configuration and parameter list files and check they meet your needs. In case different selections or configuration parameters are needed, it may be better to produce a new and more suitable catalogue, or to produce a new chi2 image. TERAPIX can provide specific help to users who want to produce their own images or catalogues. 94
