GamaTiling_v1.fits (version June 11, 2010) contains the tiling catalog sources for GAMA. This is a public release version of the TilingCatv09.fits that has had the S,Z,Q, speccats_id, Radio_Flux and areaflag columns removed. The latter is deprecated, the first 4 can be found in GamaCoreDR1 (with the names Z_SOURCE, Z_HELIO, Z_QUALITY and Z_ID) Derived from InputCatA, selecting GAMA regions (4x12), applying magnitude limits, star-galaxy separation, SB limits, and mask. Note addition of vis_class=4 for compromised photometry. These objects are now excluded from the science catalogs defined by survey_class. For science catalogs: select, for example, SURVEY_CLASS >= 3 for r<19.8, z<18.2 or K_AB<17.6 selection, SURVEY_CLASS >= 4 for main survey targets (see IC paper), SURVEY_CLASS >= 6 for r-selection only (r<19.4 in G09 & G15, r<19.8 in G12). main survey (MS) = (r<19.4 (G09,G15) or r<19.8 (G12) or K_AB<17.6 or z_{model}<18.2) IC paper http://adsabs.harvard.edu/abs/2010MNRAS.404...86B The redshifts are obtained by matching to SpecCatalogsv06. Matches are within 1 arcsec except for a few cases. The spectrum with highest Q value is used in case of multiple matches. In case of equal Q, the spectrum with the highest value of PROB - DIST is used (where DIST is the matching distance in arcsec with a minimum of 0.1 arcsec). ............................................................................... 169850 rows Column details in .par file. Expanded explanation of some columns below. ............................................................................... VIS_CLASS for visual classification 0 = not eyeballed 1 = yes a target 2 = not a target (no evidence of galaxy light) 3 = not a target (not the main part of a galaxy) 4 = compromised photometry (selection mag has serious error) 255 = not eyeballed but the following flags are *all* zero EDGE, BLENDED, CHILD, MAYBE_CR, MAYBE_EGHOST ............................................................................... TARGET_FLAGS (t) (showing which target criteria are satisfied) (bitwise set of flags, bit X): X 2^X meaning 0 1 SDSS main galaxy sample 1 2 SDSS LRG sample 2 4 r<19.0 and r_psf-r_model>0.25 (high priority in Year 1) 3 8 r<19.4 (G09,G15) or r<19.8 (G12) 4 16 r<19.8 5 32 z_model<18.2 6 64 K_AB<17.6 7 128 (g_model<20.6 or r_model<19.8 or i_model<19.4) (G12) 8 256 radio_flux>0.0 ............................................................................... SURVEY_CLASS (s) s=0: not a target (except for checks on vis_class=3) s=1: target only because of radio selection (F1 not (MS or F2 or F3)) s>=2: passes star-galaxy separation criteria (MS, F2 or F3) s>=3: r<19.8 or zK-selected (MS, F2) (uniform selection in all regions) s>=4: *** MS *** s>=5: MS r or z-selected s>=6: *** MS r-selected only *** s>=7: r<19.0 and sg_sep>0.25 (Year 1 high priority targets) See 'Input catalogue and star-galaxy separation' (IC) paper for details on selection. MS is main survey; F1, F2, and F3 are filler selections. Further note: Objects with target_flags=0 (also survey_class=0) have 2<=vis_class<=4 or they are excluded by Eq. 12 only of the IC paper (Sec. 5.2). These remain in the tiling catalogue because they are rejected by a more subjective criteria than the other selections. ............................................................................... PRIORITY_CLASS (p): *** Only applying to main survey *** p=9: Q<=2 and num_gama_spec = 0 (was a target but never attempted) p=8: Q<=2 and num_gama_spec = 1 (only one failed GAMA observation) p=7: Q<=2 and num_gama_spec = 2 (two failed GAMA observations) p=6: Q<=2 and num_gama_spec >= 3 (three or more failed GAMA observations) p=5: Q<=2 and fibermag_r>22.5 (too faint, not targeted by AAOmega) p=4: Q<=2 and fibermag_r<16.86 (too bright, not targeted by AAOmega) p=3: Q=3 and not (S=1 or S=5) (mainly Q=3 old '2dF' spectra) p=2: Q=3 and (S=1 or S=5) (Q=3 with SDSS or GAMA) p=1: Q>=4 (high quality redshift) p=0: all others including other survey class, and vis_class=2 or 3 objects. ...............................................................................
