shift

Description

This program adjusts an entire shape file by a deltaX, deltaY and deltaZ. shift is typically used to adjust the center of figure to center of mass.

shift can also deal with the fact that sometimes a shape model's center of figure can drift off the 0,0,0 coordinate center, i.e. the middle of the asteroid is no longer at the origin of the system. In such cases, you can run shape_info and use its Center of Figure offsets as the input for shift.

Using shift

$/!\$ When you shift a shape file, only input the root name. Do not put in the fullpath or .TXT extension.

Here is a sample set of inputs for shift:

 Enter C0(i), i=1,3
 0.66624D-03   -0.24253D-03   -0.13943D-02
 Shape shift? (y/n)
TESTSHAPE
 Shift maplets? (y/n)
y

 GEOMETRY
20
1
n
n

do we need to annotate the code to explain these or do a writeup here about them?

Enter C0(i), i=1,3 -
Shape shift? (y/n) -
Shift maplets? (y/n) -

The final 5 lines copy and paste to update the rest of the system (updating SCOBJ and C_vector).

$/!\$ You must do this if you update the MAPLET positions.
