Getting/compiling/using imcopy

• 1) Download imcopy from

  http://heasarc.gsfc.nasa.gov/docs/software/fitsio/cexamples/imcopy.c

  Ensure that the file has saved correctly i.e. in plain text as some browsers will insert HTML tags. It might be easier to just cut/paste the page into a file.

• 2) If you have starlink try to compile imcopy against your local copy of cfitsio:
  

  gcc -I/star/include -L/star/lib -lm imcopy.c -lcfitsio -o imcopy

• 3) If that works move the imcopy executable to wherever you'd like it to be.

• 4) If you don't have starlink or step 2 didn't work. Download the latest stable version of CFITSIO for your computer here: http://heasarc.gsfc.nasa.gov/fitsio/
  The tar file should include imcopy.c

• 5) Extract
  

  tar xvfz cfitsioXXXX.tar.gz (XXXX = version of cfitsio)

• 6) Compile and install into your chosen directory, replace $INSTALLDIR with the name of your preferred directory.

  cd cfitsio
  ./configure --prefix=$INSTALLDIR
  make
  make install
  

• 7) Compile

  gcc -I$INSTALLDIR/include -L$INSTALLDIR/lib -lm imcopy.c -lcfitsio -o imcopy

• 8) Move the imcopy executable to wherever you want it to be.

• 9) Usage is

  imcopy inFileName outFileName

  e.g. to uncompress the RICE compressed file wsa_st.fit
  

  imcopy wsa_st.fit wsa_out.fit
