Subject: problem with asmooth version 2.30 in SAS16
Full_Name: Frank Haberl
Submission from: (NULL) (130.183.72.80)


Hello,
the new version of asmooth (2.30) in the distribution of SAS16.0.0 does not work
correctly for big mosaic images (in this case a 6x6 degrees SMC image with
2x2arcsec^2 pixels). It produces regular patterns in the image which point to a
problem in the new fft routine introduced into asmooth version 2.30.
Version 2.29 from SAS15.0.0 works without problems.
A screen shot showing a comparison of old/new images can be provided.
Best regards
Frank

Hello Frank,

 many thanks for the report. If you can send us the images you have that would
be helpful.

 Best wishes,

Hi Jan-Uwe,

attached the screen shot. For testing I had populated the big image only
with a few observations.
The screen shot shows a zoom into the images, one produced with SAS15
(asmooth 2.29, left),
the other one with SAS16 (asmooth 2.30, right).

Viele Gr=FC=DFe,
Frank

Dear Frank, could you also send the unsmoothed image? As you suspect, it may be
the size and using your's for testing would help us. If too large for email
attachment, perhaps you can post it on an ftp server?

 Thanks,

Hi Jan-Uwe,

sorry for taking so long. Here the input and resulting output. For the
test only a few observations were included, so only a few "islands" are
visible in the images. Asmentioned before when using the old asmooth
version everything looks fine.

Cheers
Frank

Hi Frank,

 many thanks for sending the image. amooth (v2.30) in SAS 16 works ok for
smoothstyle='simple' or smoothstyle=adaptive
on that large image.

Since you are using

smoothstyle='withset' inconvolversarray=SMC_ima_convolversset.fits
inindeximagearray=SMC_ima_indeximageset.fits varianceset=SMC_ima_invar.fits
expimageset=SMC_ima_1exp.fits expmapuse=samesnr

we are almost certainly going to need the files:

SMC_ima_convolversset.fits
SMC_ima_indeximageset.fits
SMC_ima_invar.fits
SMC_ima_1exp.fits

as well but definitely the first one. Can you also send these to us please?

Thanks,
Jan-Uwe

Dear Frank,

 many thanks for providing the input images. Richard has now studied this case
and reports the following:

============
From the files supplied SAS 15 gives the same bad final image as SAS 16.
The reason is because the file - SMC_ima_indeximageset.fits - is not right.
It should contain an integer in each pixel which represents the convolver from
the
file SMC_ima_convolversset.fits which should be used in each pixel.
At the moment the file SMC_ima_indeximageset.fits contains decimal numbers which
are the same as in the input image more or less (it has got corrupted in some
way).

The reason you get the four images of the bright central source is because the
index image is telling asmooth to use convolver number 1, which is a strange
shape with four corner elements.

If the convolver file is right, then the index image is wrong. If I set all
pixels in the index image to 50 to use convolver number 50 then it gives a
sensible(ish) answer.
============

Does that make sense to you?

Regards,
Jan-Uwe

Dear Jan-Uwe, Richard,

when I run the whole process with SAS15 everything works fine.

So my conclusion is then that SAS16 produces a wrong
SMC_ima_indeximageset.fits file (we did it several times, reproducably)
while SAS15 does it correctly.

I created a tar with the same files requested by you previously, but now
the ones created with SAS15:

ftp://ftp.mpe.mpg.de/people/fwh/asmooth_problem_SAS15.tar

Can you check if these are ok (they must be, because the smoothed image
is ok) and why the SAS16 version is different?

Thanks again
Frank
