GLO Utility Software

The software is DOS based, and the following text describes how
we run the programs on our machines.

There are the three main utility programs designed for GLO data handling:

    GLOView - Gives a diagram of the view out of the shuttle bay
	from the position of our instrument.  It is used for planning
	experiments and to review where the instrument was looking at
	any particular time.

    SIBYL - A GLO image handling program which provides access to
	the spectral and imaging data.

    SPECT - An analysis program for doing the same operations on all
        spectra in a set at the same time.  It is used  mostly for calibration.
        This program is not available at this time.

On our computers, each utility program resides in its own directory, 
with supporting sub-directories.  In addition, miscellaneous programs
and batch files are in the sub-directory \util\glo, which is the
only directory that needs to be added to the read path to run
our software.

Our directory set-up has the following structure:

    |- GLOVIEW
    |- SIBYL --------;- CAL
    |                `- MP
    |- UTIL ----------- GLO

    The CAL sub-directory contains many ascii files which give
    calibration information, etc. about the instrument and flight.

    The MP sub-directory contains mimi-programs to preform lists of Sibyl

    Note:   It is difficult to predict all the problems new users may
	    have using the data or software.  Please see our frequently
	    asked questions (FAQ) page for answers to the most common
	    questions.  If you have suggestions for our documentation or
	    other questions, please let us know.


GLOView is a graphical software package used for planning observations before and during Shuttle flights and for reviewing where the instrument was looking on previous missions.

This is a screen display for a time during STS-63. Click on the image to see an enlarged view of the screen with some of the features labelled.

The center of the display is the Shuttle -Z axis (out of the bay). The entire spatial sphere is represented, with the +Z (beneath the Shuttle) hemisphere at lower resolution.

GLOView uese data files to input the Shuttle orbit, attitude, GLO az/el, the Shuttle mask, a UV star catalog, and the user's default configuration.

*System Requirements

*Software for STS-63

A self-extracting archive of the GLOView program for STS-63 called gv-sts63.exe is available.

*Software for STS-69

+ A self-extracting archive file for GLOView program for STS-69 called gv-sts69.exe is available for downloading.


Sibyl is a command-driven program developed to handle the data returned from CCD spectrographs and imagers; in particular, data in FITS format from the Arizona Airglow Instrument (GLO). The experiment is flown under the GLO acronym and will continue in a series GLO, GLO2, etc. Sibyl is usually resident in its own directory and has subdirectories CAL and MP. The CAL directory carries all of the calibration data required to handle the data set. This includes bad pixel files (.HPX), sensitivity files (.ASC), slit straightening files (.SLT), wavelength calibration files (.WVL), regions selection files (.REG), dark frames (.FIT), etc. The MP directory carries the mini-program files which are called, edited and run in Sibyl.

SIBYL gives the most flexibility in handling single spectra. It is most convenient to call it from within the directory you wish to work. Preset paths are contained in the SIBYL.CFG file for various functions.

This is a screen display of a spectral image from STS-69. Below the image is a plot of one of the two spectra shown on the image. Click on the image to see an enlarged view of the screen with some of the features labelled.

Auxiliary programs are carried in a UTIL/GLO subdirectory which also contains the batch files for various functions. The batch file S.BAT is used in our system to call SIBYL. Internal to the file, a screen capture utility program can be called and configured to allow screen dumps from within Sibyl. We use the screen capture program GRAFPLUS.

Getting Started: A Sample Session

Go to the SIBYL directory and print out the help file SIBYL.HLP. Notice the HOT keys at the top of the file, then the command summary list, followed by the command detail. The command detail can be accessed within the SIBYL program by the HELP command. Move to and examine the files in the directory \SAM3050 and print out the list files DIR *.LST for reference. In the archive, this directory resides ins gloarchive/data/2_1208su/. You can also print out the contents of one of the files, say 095200.LST. The printer has to be in condensed print and landscape format (the length of the page). The list contains the header data from all of the spectra in the CELL 095200 that are in the data directory \2_1208. The location of the data, dir 2_1208, is indicated on line 1. Line 2 identifies the parameters in the array to follow. Line 3 identifies the first CCD image in the SET followed by the parameters from its header. RUN SIBYL Type on the command line LIST B; the response will indicate the number of spectral images in the list you have called out. Enter RMP REVS (review spectra). Note mini-program requests spectrum #2 on line #5: SP 2 s2 i1. s2 is a spectral register, i1 is an image register. The MP can be aborted by F9. Re-starting the mini-program without reading in a new list will pick up where you left off. The image display can be made larger by editing line 2 of the MP. F2 allows editing the MP. Change line 2 to: mag 1 5 SPECT. F10 saves the edit by writing to LAST.MP and runs MP. When in Edit MP, an -i will give you a new line. A - will erase a line. Type STP to exit SIBYL. To change the start position and size of the windows in SIBYL, do one of the following: 1. Edit SIBYL.CFG and hand-set the values of the window positions. 2. Position and Size the windows in SIBYL. Save a new configuration (SAVECFG command). Do NOT overwrite SIBYL.CFG--call it something else. Get out of SIBYL. Copy the position and size lines from the saved configuration into SIBYL.CFG, and remove the old lines. Increasing the number of registers increases memory usage by about 1K per register. In a tight memory situation use the least number of registers you need. To customize SIBYL, edit the SIBYL.CFG file (SIBYL configuration).
SIBYL log files are saved in the directory that SIBYL was started from. The log file has the name 'SdyMON##.LOG". (S for SIBYL, dy=day#, MON=month, ## = incrementing number sequence. An example of the third SIBYL log file created on Jan. 18 would be S18JAN02.LOG.)
