Erc- I think that the slice output may give
the wrong ra scale (for a ra slice at a fixed dec ).

I have an image and I have blc 402 430 and
trc 533 430

The final slice (after slice and sl2pl)
is plotted with a scale of k arc sec (the image
has a pa of -89.7- ran eposwitch).

If I use the scale that sl2pl gives in
kilarc sec it says that the ra of the center
is 05 34 47.171 and -05 31 34.6. The dec is fine.
But this ra cannot be right I think. I think
the ra of the center of the slice  is in fact the ra of the f c of 05 35 15.46.

Is this possible.

thanks
miller
