Can't solve most images....

[Dan Gray]

Hi all,
So far, Dustin has been extremely helpful, thanks.
Ok, making baby steps here.
I was able to solve 2 images, but most images fail.

Here's two that fail.  I'll list each image, and then the command line I'm using, and the result:
There are two M44 images that were installed in the Astrometry.net folder.  The're both Jpegs, and one has higher background, but one solves, and the other doesn't.
I've copied the three files to my website, so anyone can test them too.

This one is solved by solve-field:
sudo ./solve-field --scale-units degwidth --scale-low 0.8 --scale-high 0.9 --ra 130.132 --dec 19.64 --radius 3  --overwrite /home/dan/Astrometry/examples/m44-1975-01-18.jpg
Result=
Field: /home/dan/Astrometry/examples/m44-1975-01-18.jpg
Field center: (RA,Dec) = (130.098914, 19.683971) deg.
Field center: (RA H:M:S, Dec D:M:S) = (08:40:23.739, +19:41:02.295).
Field size: 53.5396 x 51.6443 arcminutes
Field rotation angle: up is 179.953 degrees E of N

Ok, cool, it didn't take too long either, about 12 seconds.
I really think the following should solve too.  I'm using the same command line (with different filename), but it won't solve.   What am I doing wrong?
It's a nearly identical field, M44, but has less background level......
sudo ./solve-field --scale-units degwidth --scale-low 0.8 --scale-high 0.9 --ra 150.132 --dec 19.64 --radius 3  --overwrite /home/dan/Astrometry/examples/m44-1910-04-01.jpg

In both of the above instances, I was using 4200 indexes.

Ok, those previous images came with the install of astrometry.net-0.73
I copied them here:

Solved ok:

Now here's an image I took from SAAO using their 1 meter Lesedi alt/az telescope.
http://siderealtechnology.com/Astrometry/InWest2-0007L.fit
The coordinates for this image (I solved it with Dave Rowe's Platesolve using WIndow) are as follows:
ra=10:13:13.993  dec=-21:55:33.93
OR in decimal degrees:
ra=153.308304 Dec=-21.926092
F.O.V. =
9.8 arc minutes by 6.45 arc minutes. 
In deg's it's:
0.1645 x 0.109.

Here's the command line that *Should* solve it?
sudo ./solve-field --scale-units degwidth --scale-low 0.09 --scale-high 0.2 --ra 153.3 --dec -21.926 --radius 2  --overwrite /home/dan/InWest2-0007L.fit


Here's a screenshot of a successful PlateSolve of the above image using PlateSolve by Dave Rowe (from planewave.com) under windows.
http://siderealtechnology.com/Astrometry/PlateSolveScreenShot.jpg

It was also solved by http://nova.astrometry.org....  Here's a screenshot of that:

Does anybody have any suggestions?
Thanks....

P.S.
Here's my configuration file:

Hi,

Thanks for your patience.

If you've got the plotting code built (looks like not), then it's usually helpful to make sure the source extraction (star detection) worked right.  The nova.astrometry.net web site, by the way, recognizes both of these, the 1975 image with index 4107, the 1910 with index 4109.  The web site by default uses "--downsample 2".  These images are pretty chunky, so I went with:

solve-field demo/m44-1910-04-01.jpg -L 0.8 -H 0.9 --downsample 4
solve-field demo/m44-1975-01-18.jpg -L 0.8 -H 0.9 --downsample 4

and got pretty quick solutions for both.

For your FITS image, similarly, I get o solution with "--downsample 2".

cheers,
--dustin

Thanks Dustin,

cairoutils.c:715:cairoutils_read_ppm_stream: Netpbm is not available; can't read PPM images
libpng warning: Image width is zero in IHDR

solve-field.c:326:plot_source_overlay Plotting command failed

I found my netpbm files:
/user/bin
and /user/include

So I issued the following commands:
 export NETPBM_LIB="-L/usr/bin -lnetpbm"
 export NETPBM_INC="-I/usr/include/netpbm -I/usr/include"
those commands are now in my  environment
Then I issued:
make reconfig
The output looks good, but I still get
the errors "Netpbm is not available; can't read PPM images"
Do you have any suggestions?

Here's the output of the make config
Config results:
------------------------------

cat makefile.os-features
# This file is generated by util/Makefile.
HAVE_NETPBM := yes

------------------------------

And, by the way, is WCSlib support being compiled in?

pkg-config --exists wcslib && echo yes || echo no
no

  WCSLIB_INC:
  WCSLIB_LIB:

------------------------------
make[1]: Nothing to be done for 'config'.
make[1]: Leaving directory '/home/dan/astrometry.net-0.73/util'

I added the -downsample 2 and ALL of the images solved in just a few seconds!
Thanks a million!
Now I'll start a new thread about the:

Hi,

The NETPBM_LIB tells it where to find *library* files, not executables, so you probably want instead:

export NETPBM_LIB="-L/usr/lib -lnetpbm"

and then after a "make reconfig", do a "make" and "make extra".

cheers,
