As you pointed out, actual aim points of SAX J1808.4 and H 1743 during their observations were HXD nominal and XIS nominal, respectively, which were what the ToO team requested. However, the NOM_PNT keyword in the data files and hence aim points on the DARTS page were put wrongly.This was a human error which had not happened in previous operations. The operation team will take a measure to prevent this kind of error, and the information in the DARTS page will be corrected. When you analyze these data, please be careful to use correct responses.
