Description of the files required and created by int_status

The int_status (includes in integral package) allows us to obtain the coordinates files required to the reconstruction of the images. For do it, you have to run int_status inside IRAF (see chapter 3).

The files required for int_status are:

• The file databundles.txt, which basically contains the names of the input files required for int_status.

• The files SB1.status, SB2.status and SB3.status (one for each bundle). These files contain two columns: #fibre and FS, where FS is the current fibre status (broken: 0, no broken:1).

• The files SB1.data, SB2.data and SB3.data. These files contain four columns: #fibre, x(arcsec), y(arcsec) and fibre type. This parameter defines object fibres (distributed over the rectangular central region of the bundle) and sky fibres (distributed over the external ring of the bundle).

You must no change the files with `data' extension, but you have to know the current status of each fibre. In principle, the support astronomer should edit the files with extension `status' in order to change the fibre status (non-broken $\Rightarrow$ broken) if this was necessary.

The files generated by int_status are:

• SB1.coor, SB2.coor and SB3.coor. These files contain four columns: #fibre (number of fibre), x(arcsec), y(arcsec) and fibre status. The parameters x and y are the fibre coordinates in arcsec at the focal plane, fibre status defines the current status of each fibre (broken: 0, non-broken:1), and #fibre is the fibre number. The number of rows of these files corresponds to the number of fibres of each bundle which are object type (those of the rectangular central region of each bundle). These files are necessary for perform a image reconstruction.
• SB1.pix, SB2.pix and SB3.pix. These files are very useful in order to display with tvmark task some of the INTEGRAL bundles (circumferences with center at the fibre position and the fibre radius for each one of the observing fibres) over an image.
