          The other parameters  (or  command  line  options),  if
          present,   override  these  defaults.   The  choice  of
          "other" uses defaults that are the same as "wb".

     _l_p_c__m_e_t_h_o_d - _s_t_r_i_n_g
          The analysis method used to compute reflection  coeffi-
          cients.  This parameter is not read if the ----aaaa is used.

     _d_a_t_a__w_i_n_d_o_w - _s_t_r_i_n_g
          The data window to apply to the data.   This  parameter
          is  not read if the ----dddd option is specified or if _m_e_t_h_o_d
          is in the parameter file and does not  have  the  value
          "other".   Acceptable  values include "RECT" for a rec-
          tangular window, "HAMMING", for Hamming, "HANNING"  for
          Hanning,  "COS4" for cosine 4th, and "TRIANG", for tri-
          angular; see the _w_i_n_d_o_w(3-ESPSsp) manual page  for  the
          complete list.

     _s_t_a_r_t - _i_n_t_e_g_e_r

          The first point in the input sampled data file that  is
          processed.   A  value  of 1 denotes the first sample in
          the file.  This parameter is not read  if  any  of  the
          range  command  line options are used.  If it is not in
          the parameter file, and neither option is specified,  a
          default value of 1 is used.

     _n_a_n - _i_n_t_e_g_e_r

          The total number of data points to process.  If _n_a_n  is
          0,  processing  continues  through the end of the file.
          This parameter is not read if any of the range  command
          line options are used.

     _w_i_n_d_o_w__l_e_n - _f_l_o_a_t

          The duration in milliseconds of each frame. This param-
          eter  not  read  if  the  ----wwww  option is specified of if
          _m_e_t_h_o_d is in the file  and  does  not  have  the  value
          "other".

     _p_r_e__e_m_p_h_a_s_i_s - _f_l_o_a_t
          The coefficient in the preemphasis filter (see  ---- EEEE  in
          the Options section). This parameter not read if the ----EEEE
          option is specified.

     _s_t_e_p__s_i_z_e - _f_l_o_a_t
          Initial points of consecutive  frames  differ  by  this
          number of milliseconds.  This parameter not read if the
          ----SSSS option is specified.

     _o_r_d_e_r - _i_n_t_e_g_e_r

          The number of reflection coefficients computed for each
          frame of input data.  If no value is given in the file,
          a default value of 15 is used.  This value is not  read
          if the command line option ----oooo is used.

     _s_t_r_c_o_v__t_e_s_t - _f_l_o_a_t

          If STRCOV is used, this is the convergence  test  value
          (the lower the value, the smaller the change per itera-
          tion before termination). This is not  read  if  ----cccc  is
          used.

     _s_t_r_c_o_v__m_a_x_i_t_e_r - _i_n_t

          If STRCOV is used, this is the maximum number of itera-
          tions allowed before the estimator terminates.  This is
          not read if ----iiii is used.

     The values of parameters obtained from  the  parameter  file
     are printed if the environment variable ESPS_VERBOSE is 3 or
     greater.  The default value is 3.

     ESPS Common is  read  provided  that  Common  processing  is
     enabled  and  that  the  _f_i_l_e_n_a_m_e  entry  in  Common matches
     _i_n_p_u_t._S_D, in which case parameters present in  Common  over-
     ride  values  from  the parameter file, which in turn may be
     overriden by command line options  (see  the  discussion  in
     ESPS  PARAMETERS  and under each option).  Common processing
     is useful when _r_a_n_g_e (1-ESPS) is used to  select  a  segment
     from  _f_i_l_e._s_d.  Common  is  not  read if _f_i_l_e._s_d is standard
     input. If _f_i_l_e._r_c is not standard output and _f_i_l_e._s_d is  not
     standard  input, the Common parameters _f_i_l_e_n_a_m_e (= file.sd),
     _p_r_o_g (= refcof), _s_t_a_r_t, and _n_a_n are written to ESPS Common.

     ESPS Common  processing  may  be  disabled  by  setting  the
     environment  variable USE_ESPS_COMMON to "off".  The default
     ESPS Common file is setting the environment variable ESPSCOM
     to  the desired path.  User feedback of Common processing is
     determined by the environment variable ESPS_VERBOSE, with  0
     causing  no  feedback and increasing levels causing increas-
     ingly detailed feedback.  If ESPS_VERBOSE is not defined,  a
     default value of 3 is assumed.

     The generic header item _s_t_a_r_t__t_i_m_e (type DOUBLE) is  written
     in the output file.  The value written is computed by taking
     the _s_t_a_r_t__t_i_m_e value from the header of the input  file  (or
     zero,  if such a header item doesn't exist) and adding to it
     the offset time (from the beginning of the  input  file)  of
     the  first  point  processed.  Also, the generic header item
     _r_e_c_o_r_d__f_r_e_q (type DOUBLE) is written  in  the  output  file.

     The  value  is  the  number  of output records per second of
     input data.  For details on the parameters used  by  all  of
     the  programs in the script, look at all of the intermediate
     headers (e.g., via _p_s_p_s ----aaaa).
