             How to Make ansa Observation List Files


RTS (UVS/EUV)
-------------

1) First, the RTS packet times files need to exist.  They are created with the
programs diskh:[gllseq.software]uvs_packet_times.pro and
diskh:[gllseq.software]euv_packet_times.pro.  

The files created by these programs should live in glluvs2:[gllseq.xx.yyy], 
where

   xx = two letter orbit  (ex. 15)
   yyy = three letter orbit  (ex. 15A)

and the file name is (uvs/euv)_pkt_times.zzzzzz, where

   zzzzzz = four letter orbit + version (ex. E15AHA) 

See HOW_TO_CREATE_RTS_PACKET_TIMES_FILE.DOC for more details.

2) Now the (uvs/euv)_pkt_times.zzzzzz files should be copied to files with
names obs_named_(UVS/euv).zzzzzz and hand edited to block off observations.

Example:  UVS_PKT_TIMES.E16AKA
--------
UVS
GLLUVS2:[GLLSEQ.16.16A]SEF_980624.strip_E16AKA
 
start    end       delta   command     utc end time (GMT)
---------------------------------------------------------
4572266 4572310      44     6UVRT   1998-202/21:09:47.770
 
4572311 4572350      39     6UVRT   1998-202/21:50:14.435

4572356 4572360       4     6UVRT   1998-202/22:00:21.101
 
4572361 4572365       4     6UVRT   1998-202/22:05:24.435
 
4572366 4572370       4     6UVRT   1998-202/22:10:27.768
 
4572371 4572421      50     6UVRT   1998-202/23:02:01.766

4572422 4572426       4     6UVRT   1998-202/23:07:05.099
 
4572427 4572431       4     6UVRT   1998-202/23:12:08.43


Example: UVS_PKT_TIMES.E16AKA becomes OBS_NAMED_UVS.E16AKA


UVS
GLLUVS2:[GLLSEQ.16.16A]SEF_980624.strip_E16AKA
 
start    end       delta   command     utc end time (GMT)
---------------------------------------------------------  BRIGHT01
4572266 4572310      44     6UVRT   1998-202/21:09:47.770

3) The ansa list files are created by the idl program

idl> .run diskh:[gllseq.software]create_rt_querylist.pro
idl> create_rt_querylist

which reads the obs_named_(UVS/euv).zzzzzz files.  The output file is named 

xxxx_(euv/uvs)_rt.lis where

   xxxx = four letter orbit (ex. e16a).

This file has the format:

       Observation        Start       End
-------------------------------------------
1)      BRIGHT01         4572266    4572350
2)      FEATUR01         4572356    4572431
3)      BRIGHT03         4572432    4572512


4) FTP xxxx_(euv/uvs)_rt.lis to ansa with pathname

/ansa2/gll_raw/lrsp/pkt_times/xxxx_(euv/uvs)_rt.lis.


UVS PBT
-------

1)  Check if the playback table is at lasp.  It lives in 
glluvs2:[gllseq.xx.yyy], where

   xx = two letter orbit  (ex. 15)
   yyy = three letter orbit  (ex. 15A)

with filename PBT_zzzzzz.UNI_aaaaaa, where

zzzzzz = Creation date (ex. 980604)
aaaaaa = three letter orbit + P + version (ex. E15PCB)

(see HOW_TO_PROCESS_SEQUENCES.DOC for more details)

If the playback table is missing or out of date, retrieve it from donatello.

Example:
--------

>ftp donatello.jpl.nasa.gov
Name (donatello.jpl.nasa.gov:sweet): ksimmons
331 Password required for ksimmons.
Password:
230 User ksimmons logged in.
ftp> cd /e16/pbt/current
ftp> get pbt.e16pba
ftp> bye

Put the playback table in the above directory with the correct naming
convention.

2) Run the idl program

idl> .run diskh:[gllseq.software]pbt_strip.pro
idl> pbt_strip

There are two output files:

xxxx_playback_table.lis - playback table for pb notebook

xxxx_uvs_pb.lis - file to ftp to ansa

where

   xxxx = four letter orbit (ex. e15a)

3) FTP xxxx_uvs_pb.lis to ansa with pathname

/ansa2/gll_raw/lrsp/pkt_times/xxxx_uvs_pb.lis.
