The dot-dashed lines correspond to (from the innermost) 68%, 95% and 99% best fit confidence level contours for the HESS J1943+213. The positions of the possible counterparts are indicated: the partial circle in green/light grey is the (large) INTEGRAL error circle for IGR  19443+2117; the red/grey solid circle is radio beam size with NVSS J194356+211826 in center; the blue/grey dashed circle is the NRT position; the small magenta/grey solid circle is the ROSAT 90% position circle with 1RXH J194356.2+211824 in center; the triangle is used for NVSS position; the blue square is used for BAT position; the star is used for both CXOU J194356.2+211823 and 2MASS J19435624+2118233.
