Function: Exports to a file the values of radial velocities, FWHM or pixel shifts of fxcor task.
Syntax: readfxcor fxcorfile rvfile pattern bundle
Parameters:
Description:
With this task we can extract the velocities, FWHM or shifts in pixels from the ``.txt'' suffix text output file, which contains these parameters in the standard IRAF 'list' format.
The output file has the same structure of an input file of int_map task (see next section): nf, x, y, parameter and status, where nf is the number of the fibre, x and y are the x-coordinate and the y-coordinate of the fibre at the focal plane of the telescope, parameter is the extracted value (vel/fwhm/pixel) corresponding to the fibre number nf and status defines if the fibre is broken (0) or non-broken (1).
