The integral package allows to INTEGRAL user to perform the reduction of the data obtained with this instrument in the IRAF environment. This package contains standard tasks of other spectra reduction packages (onedspec and specred and ccdred), and special tasks what have been developed to perform different operations with the INTEGRAL data. In particular, the INTEGRAL user dispose of several integral tasks (e.g.: int_rec) for the on-line reduction of the images.
Some of these tasks contain FORTRAN programs, which has been implemented inside the IRAF environment with the IMFORT Interface (see A User's Guide to Fortran Programming in IRAF. The IMFORT Interface. Doug Tody. NOAO. September 1986).
This manual includes: i) the integral tasks for a quick data examination and on-line data reduction during observing, and ii) the steps (and tasks) to perform the INTEGRAL Data Reduction.
