"NAME\n"
"       sp_extract - spectrum extraction\n"
"\n"
"SYNOPSIS\n"
"       sp_extract [options] <infiles>\n"
"\n"
"DESCRIPTION\n"
"       The  command  extracts a spectrum at a given position in a\n"
"       combined image.  The command takes as parameters an  input\n"
"       image name, a table name and the position of the spectrum.\n"
"\n"
"ALGORITHM\n"
"       The following steps are performed:\n"
"       1/ Wavelength calibration using the physical model.\n"
"       2/ Extracts the spectrum and gets rid of the residual sky.\n"
"       3/ Write the result in a TFITS table.\n"
"       4/ Display the result with gnuplot.\n"
"\n"
"OPTIONS\n"
"       --output or -o outfile\n"
"              to specify the output file base name\n"
"\n"
"       --width or -w\n"
"              to specify the spectrum width.\n"
"\n"
"       --sky_dist or -d\n"
"              to  specify  the distance of the estimated residual\n"
"              sky.\n"
"\n"
"       --sky_width or -s\n"
"              to specify the width of part of the image  used  to\n"
"              estimate the res. sky.\n"
"\n"
"       --spec_pos or -p pos\n"
"              pos is the position where the spectrum is. Default is 512\n"
"\n"
"       --nograph or -n\n"
"              Flag to disable the output graph\n"
