How do I get plotting to work?

[Menno Van leeuwen]

Hello,

I am having troubles getting plotxy or the others to work.
It does process my image and show the RA and Dec correctly but I don't get any output with those circles and such.
I am receiving this error before it starts solving though.

I also included my output files of the solving maybe its of use.
Anyway I hope someone can explain or help me on how to fix this.

Hi,

The plotting requires the "netpbm" library to be found and linked.  This can be a bit fiddly to get working.

I do this (in my ~/.bashrc file):

export NETPBM_LIB="-L/usr/local/lib -lnetpbm"
export NETPBM_INC="-I/usr/local/include/netpbm -I/usr/local/include"

The exact paths will depend on where you (or your distribution) have installed the netpbm libraries and headers.

After you have done that, you will need to recompile the Astrometry.net code:

make reconfig

and if everything has gone correctly, it should end with:

...
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
yes

  WCSLIB_INC: -I/usr/local/Cellar/wcslib/5.7/include/wcslib
  WCSLIB_LIB: -L/usr/local/Cellar/wcslib/5.7/lib -lwcs -lm

------------------------------
make[1]: Nothing to be done for `config'.
>

and then

make
make extra


Good luck,

One more question, how do I get the names to be in the plot file?
Right now I only get red circles and green lines and circles but I would like to see the names of the objects in screen is that possible?

Cool, thanks for the update.

There should be three plots for solved images: *-objs.png shows just sources detected in your image, *-indx.png shows those red circles plus green ones for sources from the reference catalog, and *-ngc.png is the annotated plot.

There is a better script for making annotated images, with controls for more things -- "python blind/plotann.py".

cheers,
