Hello,<br>
<br>
I have been running DECONV.FOR for some time and its output always
seemed fine.<br>
I guess the current version - 31DEC25/APL/SUB/DECONV.FOR - does not
differ from the previous ones.<br>
<br>
<b>Yet, I am a bit confused about its output when the convolved
source is aligned with the restoring beam.</b><br>
<u>Then the returned, i.e. deconvolved, position angle is 90° larger
than those position angles.</u><br>
<br>
E.g. <br>
<i>deconv(7.1941910149411346, 6.826481869094818, 86.02929942633546,
5.699093590220353, 4.181319049159876, 86.7612722265415)</i><br>
returns <br>
<i>(5.396174907684326, 4.390378952026367, 177.1446533203125, 0)<br>
</i>So rpa=<i>177.1446533203125</i> is 90° larger than one would
expect.<br>
Could you please help me to explain this?<br>
<br>
Kind regards,<br>
Hanno Spreeuw<br>
<br>
PS To reproduce using Python, see the attached source file, which is
the original DECONV.FOR with a few additions for f2py.<br>
<i>python -m numpy.f2py -c DECONV.FOR -m deconv_python<br>
ipython<br>
import numpy as np<br>
import deconv_python<br>
# print(deconv_python.deconv.__doc__)<br>
deconv_python.deconv(7.1941910149411346, 6.826481869094818,
86.02929942633546, 5.699093590220353, 4.181319049159876,
86.7612722265415)<br>
