Release notes for ISDAT 2.3.2.

Documentation is available from irfu.irfu.se by anonymous ftp
in directory pub/isdat/doc, the file pub/isdat/doc/README
lists the documents.
The information can also be accessed using your favorite
web browser to connect to http://www.irfu.se/isdat.


ISDAT package (isdat-2.3.2.tar.gz)
==================================

Available from irfu.irfu.se by anonymous ftp in directory pub/isdat.

To install:
gzcat isdat-2.3.2.tar.gz | tar xf -
install any extra instrument modules, see below
cd isdat
make isdat


1)
You may want to customize the config file for your computer:
isdat/config/cf/sitesun5.cf for Solaris 2.x
isdat/config/cf/sitehp.cf for HP-UX
isdat/config/cf/siteosf1.cf for DEC OSF1

The features you may need to disable is:
HasCplusplus
HasFortran
HasSunPhigs
HasSiPhigs
HasIdl
HasPurify


2)
You must install the CDF library to build ISDAT, the IGR
client depends on it.
The default configuration files expects it in /opt/cdf.
You can either get the source from ncgl.gsfc.nasa.gov
or get the precompiled archive cdf-2.5-sol2.4.tar.gz
from the WEC ftp server at irfu.irfu.se in the isdat
directory (same place as the ISDAT distribution).
To unpack, do:

cd /opt
gzcat cdf-2.5-sol2.5.tar.gz | tar xf -


3)
The time manager is renamed to ctm (old name was cuitm).


4)
Igr now handles spectrograms better.
A new function have been added to the igr calculator called avg().
It will take multiple spectras and average them to one spectra.
The operators despin() and fft() have been updated and
some bugs fixed.


5)
You need to set the XUSERFILESEARCHPATH environment variable:

XUSERFILESEARCHPATH=$ISDAT/cfg/app-defaults/%N%S; export XUSERFILESEARCHPATH

If you don't you will get bad labels on buttons and menues in
some clients and ctm.



Freja F4 module (Freja4-2.3.2.tar.gz)
=====================================

Available from irfu.irfu.se in frejaftp ftp account in directory isdat.

To install:
cd isdat/server
gzcat Freja4-2.3.2.tar.gz | tar xf -
cd ..
make isdat


1)
To locate your data files you need to edit the lines

*.freja4.data:          $HOME/data/freja/data
*.freja4.index:         $HOME/data/freja/index
*.freja4.cal:           $HOME/data/freja/cal
*.freja4.log:           $HOME/data/freja/log
*.freja4.debug:         $HOME/data/freja/debug

in the file isdat/config/isdat.server.
The default directory for the data files is $HOME/data/freja/data but
can be changed by editing isdat/config/isdat.server.
The default directory for index files is $HOME/data/freja/index, if
it doesn't exist you need to create it.
You also need to create $HOME/data/freja/cal and $HOME/data/freja/log.
The time calibration file should be named $HOME/data/freja/cal/time.
The geometry information file should be named $HOME/data/freja/cal/geometry.
The time and geometry files are provided with the distribution of
the module.


2)
The module now supports the modes:

F2 all modes
F4 standard mode
F4 burst mode
F4 continuous mode LF and LFMF

SMM modes are not implemented.


3)
Use the overview client (requires PHIGS) too see which F4 signals
that are available.
You can also use fstat.
Examples of choices that gives data in the default instrument modes are:
f2 -> x -> dc
f4 -> n -> p3
f4 -> de -> p12 -> lf
f4 -> de -> pab -> hf



Wec module (Wec-2.3.2.tar.gz)
=============================

Available from irfu.irfu.se in wecftp ftp account in directory isdat.

To install:
cd isdat/server
gzcat Wec-2.3.2.tar.gz | tar xf -
cd ..
make isdat


1)
Make sure that the directory pointed to by *.cluster.index
is empty before starting the server. Old index files from
previous versions are not compatible with this version.
The index files will be built the first time a Content
is requested from the time manager.


2)
To locate your data files you need to edit the lines

*.cluster.rdm:          $HOME/data/cluster/RDM
*.cluster.dds:          $HOME/data/cluster/DDS

in the file isdat/config/isdat.server.
The value given to *.cluster.rdm needs to be a directory
with subdirectories named after the CDROM volume label.
Doing an ls -l on it should give:

drwxrwxr-x   7 al       isdat        512 May  8 23:49 950323_1_2a/
drwxrwxr-x   8 al       isdat        512 May 24 14:31 950323_2_2a/
drwxrwxr-x   8 al       isdat        512 May 24 14:31 950324_1_1a/

if all three test CDROMS from the MCT are loaded or copied.

The value given to *.cluster.dds needs to be a directory
with files named according to the specification by Per=Arne
Lindqvist. Doing an ls -l on it should give:

-rw-rw-r--   1 al       isdat     3687220 Apr 21 14:42 9511080000sh.03
-rw-rw-r--   1 al       isdat    49347219 Apr 21 14:43 9511080000wb.03
-rw-rw-r--   1 al       isdat     1426644 Apr 21 14:42 9511080000wh.03
-rw-rw-r--   1 al       isdat    14715000 Apr 21 14:42 9511080000wn.03

To look at test files from Velizy/Dornier you need to convert them
to the DDS format using the TED sistodds/tmc programs.


3)
The decommutation software is based on TED 2.2.2.


4)
When requesting HK data from a client, the DDS header is now
passed in the map array. An example is provided in
isdat/tech/wstat/main.c in the EFWHK sections.


5)
Access to the HK parameter definition (HPD) files are implemented.

An example of how to access the HPD data in a client is
provided in isdat/tech/wstat/main.c in the EFWHPD sections.
The content of the HPD file with the DDS header stripped off is
passed to the client as data. The DDS header (15 bytes) is passed
in the map array.

Access to the HPD data from within the server is possible
from the Orbit structure, the whole HPD file is read into a string
by the WEC module before any data extraction function gets called.

pOrbit->fs[hpd_file].buf	DDS packet header followed by null terminated
				HPD string
pOrbit->fs[hpd_file].ptr	null terminated HPD string
pOrbit->fs[hpd_file].size	size of string excluding terminating null
pOrbit->fs[hpd_file].n		size of string including terminating null
pOrbit->fs[hpd_file].time	DDS header time stamp

If size or n is zero no HPD data is available.
The hpd_file must be one of FILE_ED, FILE_FD, FILE_CD,
FILE_PD, FILE_RD, FILE_WD, FILE_AD, FILE_SD
for EDI, FGM, CIS, PEACE, RAPID, WEC, ASPOC and SPACECRAFT respectively.


6)
There is a status client to display WEC housekeeping data written
by Simon Walker. It is started from ctm as Clients->cluster->hkeep.
The WEC housekeeping can also be viewed in igr by selecting the hkeep
instrument.


7)
There is a status client to display EFW status data. It is started
from ctm as Clients->cluster->efwstat.
If no status is available the text area is cleared.
