The output file is sent to standard output.Each reflection coefficient.I rcis converted to a log area ratio .I laraccording to the formula.nf	\fIlar = \fRlog [(1 + \fIrc\fR)/(1 - \fIrc\fR)].fiwhere the logarithm is to base 10.  The reflection coefficients in .I rcfileare separated from each other by blanks, tabs, or newlines.  Thelog area ratios in .I larfileare separated by newlines.  If.I rcfileis omitted or equal to "\-", then standard input is used. If.I larfileis omitted or equal to "\-", standard output is used.  .SH OPTIONS.PPNo options are supported..SH "SPS PARAMETERS".PPThe SPS parameter file is not read by .I rc2lar..SH SPS HEADERS.PPNo SPS files are read or written by .I rc2lar..SH "FUTURE CHANGES".PP.SH "SEE ALSO".PPSPS (5-SPS), SD (5-SPS), record (1-SPS), copysd (1-SPS) .SH "WARNINGS".PPA warning is printed whenever a reflection coefficient.I rcsatisfies \fIrc\fP >= 1 or \fIrc\fP <= -1.  .SH "BUGS".PPNone known..SH "AUTHOR".PPManual page by John Shore.
