SYMPOW(1)			 SYMPOW package 		       SYMPOW(1)

NAME
     sympow - SYMPOW program

SYNOPSIS
     sympow [options]

DESCRIPTION
     Mathematical  package to compute special values of SYMmetric POWer elliptic
     curve L-functions (up to about 64 digits of precision).

OPTIONS
     -bound #
	    an upper BOUND for how many ap to compute

     -info [] []
	    only report local information for  primes/sympows  1st  argument  is
	    prime range, 2nd is sympow range

     -local
	    only report local information (bad primes)

     -curve []
	    input a curve in [a1,a2,a3,a4,a6] form

     -label []
	    get a label to the given curve

     -quiet
	    turn off some messages

     -terse
	    turn on some messages: default

     -verbose
	    turn on extra messages

     -rootno #
	    compute the root number of the #th symmetric power

     -moddeg
	    compute the modular degree

     -analrank
	    compute the analytic rank

     -sloppy []
	    for use with -analrank; have X sloppy digits

     -nocm  abort if curve has complex multiplication

     -noqt  ignore even powers of non-minimal quad twists

     -noqdcheck
	    don't check if quad-double stuff works

     -mdspeed []
	    speed for moddeg; 2.0 is default, 0.0 is proof

     -hecke
	    compute Hecke symmetric powers for a CM curve

     -maxtable
	    set the max size of factor tables: 2^27 default

     -sp []
	    argument  to  specify which powers this is a comma separated list in
	    each entry, the 1st datum is the sympow  then  could  come	b  which
	    turns  Bloch-Kato  on  then  could	come w# which specifies how many
	    tests then could come s# which says # sloppy digits then  must  come
	    p#	which specifices the precision or P# which says ignore BOUND for
	    this power then must come d# which says the derivative bound  or  D#
	    which  says  do  only this derivative (neither need be indicated for
	    even powers) default is 2w3s1p32,3bp16d1,4p8

     -new_data []
	    will compute inverse Mellin transform mesh for the given  data:  the
	    format is [sp]d[dv]{h,c} sp is the symmetric power, dv is the deriv-
	    ative,  h  indicates  Hecke powers, and c indicates CM case d[dv] is
	    given only for odd or Hecke powers Examples: 1d3 2 2d1h 3d2 4 4c 5d0
	    6 7d0h 11d1 12c NOTE: new_data runs a shell script that uses GP

     -dump-endiantuple
	    display the endian-tuple, used as a component  in  the  binary  data
	    paths, and exit

     -dump-versiontuple display the version-tuple (Major.minor.micro) and exit

     -version
	    print program version and exit

     -help  display this help and exit

     Other options are used internally/recursively by -new_data
