A mid-IR source catalogue of the AKARI NEP-Deep field (Takagi+, 2012) ================================================================================ The AKARI NEP-Deep survey: a mid-infrared source catalogue Takagi T., Matsuhara H., Goto T., Hanami H., Im M., Imai K., Ishigaki T., Lee H.M, Lee M.G., Malkan M., Ohyama Y., Oyabu S., Pearson C.P., Serjeant S., Wada T., White G.J. =2012A&A...537A...24T ================================================================================ ADC_Keywords: Infrared sources ; Photometry, infrared Mission_Name: AKARI Keywords: infrared:galaxies - surveys - catalogues - methods:data analysis Description: The InfraRed Camera (IRC) onboard AKARI has a comprehensive mid-IR wavelength coverage with nine photometric bands at 2-24 micron. We designed the catalogue to include most of sources detected in 7, 9, 11, 15, and 18 micron bands, and found 7284 sources in a 0.67 square degree area. Here we distribute two catalogues; a mid-IR source catalogue and a supplemental catalogue including optical and near-IR photometry of optical counterparts. The mid-IR source catalogue includes photometric results with all of the IRC bands. The supplemental catalogue is based on the optical identification with a deep optical image of Subaru/S-cam, covering a part of the NEP-Deep field. See the reference for details of the NEP survey and data reduction.

Note (2): -1.00e+00 for FLUX indicate sources outside the observed field in each band. Non-detections are indicated by 0.00e+00. Note (3): Flag to discriminate between galaxies and stars, also to indicate the classification method. 0 = galaxies 1 = stars selected with their near-IR colours 2 = bright stars indicated by mid-IR colour and brightness. 3 = sources near the planetary nebula NGC6543, which are mostly the fragments the nebula (i.e. galactic objects). Note (4): Group ID for sources with close neighbours within 5 arcsec. 0 indicates isolated source. Sources in group should be treated with caution. -------------------------------------------------------------------------------- Byte-by-byte Description of file: AKARI-NEPD-SUP-V1.txt -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 11 I11 --- OBJID Source ID 12- 21 A10 --- OBJNAME_ORG Original source name in the reference 22- 33 F12.5 deg RA Right Ascension (J2000.0) 34- 45 F12.5 deg Dec Declination (J2000.0) 46- 53 F8.1 sec dSec Angular separation between mid-IR and optical 54- 63 F10.2 mag umag u* magnitude [CFHT/Megacam] (5) 64- 73 F10.2 mag e_umag u* magnitude error 74- 83 F10.2 mag Bmag B magnitude [Subaru/S-cam] (5) 84- 93 F10.2 mag e_Bmag B magnitude error 94-103 F10.2 mag Vmag V magnitude [Subaru/S-cam] (5) 104-113 F10.2 mag e_Vmag V magnitude error 114-123 F10.2 mag Rmag R magnitude [Subaru/S-cam] (5) 124-133 F10.2 mag e_Rmag R magnitude error 134-143 F10.2 mag imag i' magnitude [Subaru/S-cam] (5) 144-153 F10.2 mag e_imag i' magnitude error 154-163 F10.2 mag zmag z' magnitude [Subaru/S-cam] (5) 164-173 F10.2 mag e_zmag z' magnitude error 174-183 F10.2 mag Jmag J magnitude [KPNO2.1/FLAMINGOS] (5) 184-193 F10.2 mag e_Jmag J magnitude error 194-203 F10.2 mag Ksmag Ks magnitude [KPNO2.1/FLAMINGOS] (5) 204-213 F10.2 mag e_Ksmag Ks magnitude error 214-218 I5 --- N_neighb Number of optical neighbours (6) -------------------------------------------------------------------------------- Note (5): For sources outside image, magnitudes are set to -99.00.
