vtod.ksh (VTOD = VLDS To Disk)
(/export/home/avdev/cfg_mgr/bin/vtod.ksh)
30 -60 minutes
puts files on /avds/y00/vlds from flight tape

1. Put tape in vlds drive.
2. Rewind tape with this command; "mmt -f  /dev/sg/92 rewind" you may need
   to do it twice.
3. Type in "vtod.ksh" (or give the full path: /export/home/avdev/cfg_mgr/bin/vtod.ksh)
4. Enter fields appropriately:
 e.g.
   DIRECTORY = /avds/y00/vlds
   VLDS = C
   FLIGHT DATE = 000911
   TAPE = 01

5. A vtod log will be generated at /avds/y00/proc/log/vtod/f000911*.log
6. When vtod is finished, do a more on the vtod log
   (/avds/y00/proc/log/vtod/f000911*.log)
7. Look for coe's in the log file.
8. As vtod is running you can monitor its progress by listing out the
   directory ls -al /avds/y00/vlds/f000911t01*
9. Unload tape (mt -f /dev/sg/92 rewoffl)

exp
(/export/home/avdev/cfg_mgr/bin/exp)
60-90 minutes
expands from 12 bit to 16 bit data
1. Type in exp /avds/y00/vlds/f000911t01
   (a log file will be created /avds/y00/proc/log/exp/f000911*.log)
2. It will put the expanded .raw files in /avds/y00/raw/f000911t01*.raw
3. Make sure you have enough space
     df -k /avds   (you should have at least 12 Gb to process a full
   tape.)

pe00
/s1/rog/pe00

creates performance evaluation files for science team to peruse
1. cd /s1/rog
2. ./pe00

ql000x
(/s1/rog/ql000x)
creates quicklooks from .raw files

1. Create a list of the raw files
  e.g. ls > f.in /avds/y00/raw
2. Run the program, it will put the f000911*.ql.jpg files on /s3/ql
3. cd /s1/rog
4. It will prompt you for the file where the list of the raw files is.
   (in this case it is the f.in file which was created in step 1)
5. This will run for approx. 2 hrs.

ftp *.ql.jpg files to popo
1. cd /s3/ql
2. ftp to popo
3. On popo>  cd /ftp/pub/00qlook
4. mput f000911t01*.ql.jpg
5. Make sure you have enough space on /ftp (popo)

avmove.ksh
(/export/home/avdev/cfg_mgr/bin/avmove.ksh)
60 - 90 minutes
puts .raw files on AMASS

1. avmove.ksh f000907t01
 

update the webpage
1. start at the following URL:
     http://popo.jpl.nasa.gov/cgi-bin/avec.cgi?step=flightlog_start
2. Begin by adding the flight log and then add the runs to the flight log.
3. The files are located on popo at /cgi-bin/logs/runs
4. You'll need to ftp the completed .repl files back onto Spectra after
you've updated the web.

Remove the vlds files after you have succesfully exp-ed and avmove-ed
the data.
Always watch your space on /avds.
