XTE Patch to FTOOLS v4.1This patch updates the XTE related tools to v4.1.1 and provides
If you have RXTE data obtained in Epoch 3 (April 15, 1996 - present) for which the source count rate is less than 40 ct/sec/PCU, you should reanalyze your data using the new "L7" background model, contained in this patch, which takes into account various particle monitors and the SAA history! The new model is described in detail on the PCA pages. Briefly, characteristics of the L7-240 model include:
This patch also fixes bugs that were reported in the following RXTE tools from the FTOOLS version 4.1 release: fxbary, rddescr, mkgitf. The tool rddescr is used by pcarsp to generate response matrices. If you have had failures when attempting to generate response matrices or barycenter correct data under FTOOLS 4.1, get and install this patch. Additionally, xtefilt and its associated programs have been updated to include information about electron contamination and time since an SAA passage in the filter files. Filtering based on these quantities should result in substantially cleaner data sets with better signal-to-noise values. Instructions on installing the patch and all associated files can be found on the anonymous ftp area at https://heasarc.gsfc.nasa.gov/FTP/xte/software/xte_update The README and release notes describing significant changes to the analysis tools are also includedm. For detailed instructions about how to use the new background model and software, please see the pcabackest recipe. We expect that the new background models will encourage a flurry of publications on RXTE faint source observations. As always, if you have an article based on RXTE data accepted for publication, please drop us a note so we may include it on our web pages.
