FTOOLS: The HEASARC Sub-package The HEASARC sub-package of FTOOLS contains tasks for High Energy (X- & gamma-ray) astronomy that are not specific to a particular instrument. The following HEASARC tasks were released in the latest distribution of the HEASARC's FTOOLS package. Each task is hyperlinked to the help file distributed with the task. The same information can be obtained while running FTOOLS by typing the command fhelp {taskname}. If you require further, or more detailed information on the HEASARC sub-package of tasks, contact ftoolshelp@athena.gsfc.nasa.gov HEASARC Tasks addspec adds PHA spectra, bkgd files & combines response matrices ascii2pha Creates an OGIP FITS PHA file from an ascii dataset bincurve Bins vectors and outputs as a light curve binspec Bin spectra in vector columns chkarf Check validity of keywords in an ARF FITS file chkpha Check validity of keywords in a PHA/PI FITS file chkrmf Check validity of keywords in a RMF FITS file ecd2pha Converts Einstein HEASARC CD-ROM PHA to OGIP PHA file extractor Extracts products from input events files extrpsf Extracts radial PSF (RPSF) dataset from an event file fadmap Produce maps for SAS2 or COSB data fixregion Convert SAO region file to another coordinate system flx2xsp Creates spectra and response files from an ascii file of fluxes and errors. grppha Manipulates OGIP standard PHA FITS file gtisum Compute and list information on Good Time Intervals hkexpand Expand a compressed format housekeeping (HK) data file hkscale Scales a FITS housekeeping data file into physical values hkunexpand Compress an expanded format houskeeping (HK) data file mathpha Performs mathematical operations on PHA files mekal Generate XSPEC table file for MEKAL plasma emission model nh Return hydrogen column density for a given Ra and Dec raysmith Generate XSPEC table file for Raymond-Smith plasma emission model rbnpha Compresses a PHA dataset sf2pha Converts SF format PHA file to OGIP FITS format sky2xy Transform from sky to pixel coordinates using WCS keywords xy2sky Transform from pixel to sky coordinates using WCS keywords FTOOLS HELP DESK If FTOOLS has been useful in your research, please reference this website (http://heasarc.gsfc.nasa.gov/ftools/) and the following: Blackburn, J.
