Finish OBSID 8030, an ACIS-I observation of the hard X-ray source IGR J1305+1139 discovered by the INTEGRAL satellite, in an attempt to identify it and discover highly absorbed type 2 AGN. Then obsid 7464, an ACIS-S GTO observation of the LMXB RXS J171824.2-402934 to localize it for identifying an optical counterpart. Then 7944, using ACIS-I in the Bootes GTO survey.
