VizieR Online Data Catalog: Swift-INTEGRAL X-ray (SIX) survey (Bottacini+, 2012)

To obtain the SIX survey, we first perform independent surveys of BAT and IBIS/ISGRI in the 18-55keV energy range. Then, by combining the observations of the two instruments, we increase (sum) the exposure time. In turn the sensitivity of the SIX survey is enhanced. We compute the survey over a sky area of 6200deg² that covers the region of the north ecliptic pole (NEP) extending to the contiguous Coma region.

For the analysis presented here, we used all the available data for BAT taken from 2005 March to 2010 March.

We have used all public available data from INTEGRAL pointings as well as private data (PI: M. Ajello; proposal ID: 05K001) over seven years from the beginning of the mission (2002) to INTEGRAL revolution 829 (2009).
