AKARI/FIS All-Sky Survey Bright Source Catalogue Version 1.0 Yamamura I., Makiuti S., Ikeda N., Fukuda Y., Oyabu S., Koga T., White G.J. <ISAS/JAXA (2010)> =2010yCat.2298....0Y
ADC_Keywords: Infrared sources ; Surveys ; Photometry, infrared Mission_Name: AKARI Description: The AKARI Infrared Astronomical Satellite observed the whole sky in the far infrared (50-180µm) and the mid-infrared (9 and 18µm) between May 2006 and August 2007 (Murakami et al. 2007PASJ...59S.369M) The AKARI/FIS All-Sky Survey Bright Source Catalog Version 1.0 provides positions and fluxes for 427071 point sources in the 4 far-infrared wavelengths centered at 65, 90, 140 and 160µm (see filter characteristics in the "Note (1)" section below) Recommendation: The users of the catalogue are requested to read the documents carefully before critical discussions of the data. Any questions and comments are appreciated at ISAS Helpdesk () Please acknowledge the usage of the AKARI data (details at http://www.ir.isas.jaxa.jp/AKARI/Publications/guideline.html). File Summary:

Note (1): the filter characteristics are: ----------------------------------------------------- Filter: N60 WIDE-S WIDE-L N160 ----------------------------------------------------- Center(um): 65 90 140 160 Range(um): 50-80 60-110 110-180 140-180 Pixel("): 26.8 26.8 44.2 44.2 ----------------------------------------------------- Note (2): The sources should be referred in the literatures by their full name (AKARI-FIS-V1) followed by the letter 'J' and the objName, e.g. AKARI-FIS-V1 J0123498-025805 Note (3): Four-level flux quality indicator: 3 = high quality (source confirmed and flux is reliable) 2 = source is confirmed but the flux is not reliable (see the flags) 1 = the source is not confirmed 0 = not observed Note (4): Bit flags of data quality in hexadecimal: 1 = CDS mode used (Correlated Double Sampling used to observe bright sky regions to avoid saturation, e.g. in the inner Galactic plane) 2 = flux too low 4 = (not used) 8 = possibly a 'side-lobe' detection Combined values are represented by the sum, e.g. 9 = 8 + 1 = a possible side-lobe detection in CDS mode. Note (5): The value is 1 when the source is observed in scans separated by more than one month. This value is independent from hour confirmation and can be 1 even if the source is not confirmed (q_=1); similarly a value of 0 does not mean that the source is unreliable.
