The cleaned event files are not provided for the WAM data because the PHA to PI conversions and the event grade selection are not performed for the raw data. So you can start your WAM data analysis with the second FITS files in the directory hxd/event_uf. This directory contains three types of WAM FITS files: the BST event FITS (aexxxxxxxxxhxd_y_bstzz_uf.evt.gz), the TRN event FITS (aexxxxxxxxxhxd_y_wam_uf.evt.gz), and bstid table FITS (aexxxxxxxxxhxd_y_bstidt.fits.gz) where xxxxxxxxx is the Suzaku observation ID, y is the RPT file number which ranges from 0 to 9, and zz is sequential number of the BST data.
For example,
ae903005010hxd_1_bst01_uf.evt.gz ae903005010hxd_1_bstidt.fits.gz ae903005010hxd_1_wam_uf.evt.gz ae903005010hxd_2_bstidt.fits.gz ae903005010hxd_2_wam_uf.evt.gz
The bstid table FITS files are temporal files for time assignment in the standard pipeline processing, so are not used for the data analysis. Basically, you just have to reprocess the BST data because a wrong time is sometimes assigned for the BST data in the standard pipeline process (about 10% of all the BST data). You can check whether the time assignment is correct or not by the following command.
fkeyprint infile=ae903005010hxd_1_bst01_uf.evt.gz keynam=TIMECORR
The keyword TIMECORR can take F or T. The TIMECORR F means that the time assignment is failed, so the reprocess of time assignment should be required. The way to reprocess the BST data is shown in section 1.6. After reprocessing the BST data, you should check if the keyword TIMECORR will change from F into T.
