Name

rotcurtab - prints a table of a rotation curve

Synopsis

rotcurtab [parameter=value]

Description

This is a convenience hack for rotcurshape(1NEMO) , where it is very cumbersome to produce the rotation curve in tabular form.

Parameters

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> []

Example

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
