摘要：Using observations of Her X-1 by RXTE/PCA representing a coverage of one completeMain-On of a 35 day cycle, we have investigated the systematic variation of the shape of the 1.24 s pulse profile. Here we describe the construction of a template which provides a quantitative description of the systematic variations of the 9–13 keV pulse profile as a function of 35 day phase for aMain- On of Her X-1. Using observations of other Main-On cycles of Her X-1 by RXTE, INTEGRAL, Ginga, Beppo-SAX, Suzaku and other satellites over the last three decades, we find that these systematic variations are very stable and reproducible. The constructed template therefore allows to determine the 35 d phase for any observed Main-On pulse profile in the 9–13 keV range.
