• New task RENDER displays rendered 2d & 3d GIPSY data (feb 16, 1999)
• Linux compatibility. (February 8, 1999)
  A number of changes were made to allow GIPSY to be installed under newer versions of Linux. We tested with the RedHat 5.2 distribution which contains Linux 2.0.36, gcc 2.7.2.3 and g77 (egcs-1.0.3 release).
• PGPLOT 5.2.0 . . .         . . . and its installation problems. (November 12, 1998)
  The latest version of PGPLOT has been installed. This was a long-awaited improvement which will make a number of interesting developments possible.
  There is a problem however. Due to the increased number of modules the installation program can run out of buffer space, leaving things in a more or less indeterminate state. If this has happened, the following steps can bring the system back to normal. You must be logged in under your local GIPSY account.

  cd $gip_exe
  \rm $gip_tmp/*
  \rm $gip_sys/architecture.lock
  sed -e 's/1024/2048/g' $gip_tsk/compile.c > ./compile.c
  mv ./compile ./compile.sav
  ./compile.sav ./compile.c
  ./compile -update
  

  As an alternative, this procedure can be obtained as a C-shell script via anonymous ftp:

  cd $gip_exe
  ftp ftp.astro.rug.nl
  Name: anonymous
  Password: your email address
  ftp> cd gipsy
  ftp> get combug.csh
  ftp> quit
  
  chmod +x combug.csh
  combug.csh
  

  (This procedure is not easier, but it has a slightly smaller chance of errors)

• New features in FUNPLOT. (September 16, 1998)
  
  • an optional extra window showing the Fourier transform (FFT) of the function being explored;
  • the possibility to supply a parameter with a list of values, e.g. read from a file using the file() input function;
  • cursor read-out and the coupling of the cursor coordinates to two special parameters: XC and YC.
• New task ROTMAS. (August 14, 1998)
  ROTMAS is a program for interactive modelling of rotation curves. It has a graphical user interface (Ggi). Besides fitting the components of a rotation curve, one can also inspect how well the curve fits in a XV-diagram.
  The program includes also an interface to program ROTMOD. This is the first release of the program.
• Graphical user interface routines package (Ggi) installed. (February 19, 1998)
  For more information see the document ``Event-driven Tasks and Graphical User Interfaces''.
• New task FUNPLOT. (September 18, 1997)
  Another experimental program based on Ggi. With this program virtually every mathematical function can be explored and plotted. Parameters to the function, origin and scale of the plot can be changed interactively, the function's derivative can be plotted, etc. Like SKYTOOL, this program can be run from ngipsy, so experience with GIPSY is not required. Just type:

  ngipsy funplot

• New task SKYTOOL. (July 25, 1997)
  An interactive coordinate transformation utility based on the new experimental GIPSY graphical interface routines (Ggi). It is intended to be self-explanatory.
  It should be considered as an alpha-release/demo meant to obtain experience with Ggi. Users are explicitly invited to share their experience, comments, suggestions etc. with the author of the program (Hans Terlouw, J.P.Terlouw@astro.rug.nl).
• New task FIT. (February 19, 1997)
  Least squares fitting program for one dimensional functions.
• New task INSPECTOR. (December 17, 1996)
  This task compares interactively radial HI velocities, obtained from (fitted) 'tilted ring' circular velocities, with velocities in data slices.
• Hermes now by default attempts to start a WWW browser (March 4, 1995)
  This browser can be used to view GIPSY documentation. It also will display help information when TAB is pressed. Then the Common Output Area (COA) on Hermes' terminal screen will not be overlayed anymore.

  When the browser is terminated, Hermes will revert to displaying help information on top of the COA.

  The WWW browser can also be suppressed by putting the following line in the Hermes default file (hermes.def):

     STARTBROWSER=OFF
  

• Hypertext documentation available (29 August 1995)
  Sites which want to have a local copy of the html documentation can obtain this via anonymous ftp. See instructions. Please note that any changes are not yet distributed via the automatic update.
