GAMMA Questions

Dear Charles,

I tried to run the routine S1_deramp_TOPS_slave, but it stopped with the following error:

ERROR: cannot open S1 TOPS SLC parameter file: 20160928.iw1.rslc.deramp.par

Indeed, the par and TOPS_par file were missing for iw1 and iw2, but were available for iw3.

I looked in the script and found that you are missing two times endif, one in line 160 and one in line 205:

    if ( "$SLC_format" == "FCOMPLEX" ) then
      echo "sub_phase $SLC $dph.tmp tmp.diff_par $SLC_deramp 1 0" 
      sub_phase $SLC $dph.tmp tmp.diff_par $SLC_deramp 1 0
    else
      if ( "$SLC_format" == "SCOMPLEX" ) then
        echo "SLC_copy $SLC $SLC_par $SLC.tmp $SLC_par.tmp 3 1." 
        SLC_copy $SLC $SLC_par $SLC.tmp $SLC_par.tmp 3 1.

        echo "sub_phase $SLC.tmp $dph.tmp tmp.diff_par $SLC_deramp.tmp 1 0" 
        sub_phase $SLC.tmp $dph.tmp tmp.diff_par $SLC_deramp.tmp 1 0

        echo "SLC_copy $SLC_deramp.tmp $SLC_par.tmp $SLC_deramp $SLC_par.tmp1 2 1." 
        SLC_copy $SLC_deramp.tmp $SLC_par.tmp $SLC_deramp $SLC_par.tmp1 2 1.
    /bin/rm $SLC_par.tmp1 $SLC_par.tmp $SLC_deramp.tmp 
    endif
  endif ################################## <------------------- add this endif!

    /bin/rm tmp.diff_par
    /bin/rm $dph.tmp
    /bin/cp $SLC_par $SLC_deramp_par
    /bin/cp $TOPS_par $TOPS_par_deramp
  endif

May I also kindly suggest to code lines 115-259 (shown below) in a loop to prevent such errors? Thank you!

 if ("$nrows" >= "1") then    # for first line of $SLC_tab_slave
    set SLC=`awk '(NR==1){print $1}' $SLC_tab_slave `
    set SLC_par=`awk '(NR==1){print $2}' $SLC_tab_slave `

....

 if ("$nrows" >= "2") then   # for second line of $SLC_tab_slave
    set SLC=`awk '(NR==2){print $1}' $SLC_tab_slave `
    set SLC_par=`awk '(NR==2){print $2}' $SLC_tab_slave `
    set TOPS_par=`awk '(NR==2){print $3}' $SLC_tab_slave `

...

 if ("$nrows" >= "3") then   # for third line of $SLC_tab_slave
    set SLC=`awk '(NR==3){print $1}' $SLC_tab_slave `
    set SLC_par=`awk '(NR==3){print $2}' $SLC_tab_slave `
    set TOPS_par=`awk '(NR==3){print $3}' $SLC_tab_slave `

...

    /bin/rm tmp.diff_par
    /bin/rm $dph.tmp
    /bin/cp $SLC_par $SLC_deramp_par
    /bin/cp $TOPS_par $TOPS_par_deramp
 endif

All the best,
Julia
