[daip] SLPRT requests.

[R. Craig Walker]

I'm trying to use SLPRT on slices that are about 200 pixels long on a 43
GHz VLBA image.  I want to extract some jet widths.  The positions of the
slice points are printed to 0.001s and the Dec to 0.01".  For my slices,
the RA does not change even in the last digit over the full length of the
slice.  The Dec changes by one unit.  Not useful.  My request is to allow
greater numbers of digits in the RA and Dec.  I would also like to have
the option of getting the positions in offsets from the slice center,
which is the number I would be using in reducing the data.  My pixel size
is 25 microarcsec and the spacing of points in the slice is less than half
that, so I would need numbers printed at least to a microarcsecond.
Clearly that would cause a lot of clutter for VLA data so I suggest the
resolution be a user input.

I see that, if I save the output files from SLICE itself, I can get the
data I need via the pixel positions.  But you have to remember to do that
at the time the slice is made.

Cheers,

Craig
