rotcurtab - prints a table of a rotation curve
rotcurtab [parameter=value]
This is a convenience hack for rotcurshape(1NEMO)
, where it
is very cumbersome to produce the rotation curve in tabular form.
The
following parameters are recognized in any order if the keyword is also
given:
- radii=
- Radii where to sample the rotation curve. A nemoinp(3NEM0)
expression e.g. 1:10:0.5, are effective ways to give a large set of radii.
No default.
- rotcur1=
- Rotation curve <NAME>, and parameters []
- rotcur2=
- Rotation
curve <NAME>, and parameters []
- rotcur3=
- Rotation curve <NAME>, and parameters
[]
- rotcur4=
- Rotation curve <NAME>, and parameters []
- rotcur5=
- Rotation
curve <NAME>, and parameters []
- load=
- dynamically loadobject file with
rotcur_<NAME> []
rotcurshape(1NEMO)
Although it is possible
to create a rotation curve using rotcurshape rotcurmode=t imagemode=f on
an ascii table with given radii and 0 velocities, this is cumbersome and
also produces the negative rotation curve since it is the residual between
the data (all 0’s) and the "fit" (forcing all parameters to be 0). The following
two examples should thus be identical. First the rotcurshape method:
% nemoinp 0:10 | tabmath - - 0.0 > rotcur0.tab
% rotcurshape rotcur0.tab resid=rotcur1.tab rotcur1=core,100,2,2,0,0,0 rotcurmode=t
imagemode=f
## actually, this appears broken now,
and the rotcurtab method: % rotcurtab 0:10 rotcur1=core,100,2,2 > rotcur2.tab
