1. Instrument Status On/Off Cycle: 26 Hours On: ~47000 hours
Continuously on since 1/15/2005 (probe relay)
HDAC Filament Modulation:
Filament 1: hours (including T9)
Filament 2: hours
UVIS TEAM MEETING 1/2006

2. FSW Status ISA Z70771 ISA Z86939 (bad EUV data in S11 icylon)
Fixed by FSW patch in C24
Fixed by FSW V1.3 starting C31
ISA Z86939 (bad EUV data in S11 icylon)
Probably FSW problem
Affects all icylon in S11 and the first icylon in S12
Workaround by updating the instrument setup
No progress since last team meeting
UVIS TEAM MEETING 1/2006

3. GSW Issues No new ground software problem
Still need to re-ingest in DAPS data affected by report # 38 (EUV and HDAC records are coalesced in DAPS)
UVIS TEAM MEETING 1/2006

4. Operational Issues No new operational issues Data is partially zeroed
Not enough time left between end of last integration and next trigger
We have developed a program to identify and minimize trigger/integration timing issues
UVIS TEAM MEETING 1/2006

5. Planning/Sequencing Issues
No new Planning/Sequencing issues.
When a setup is not defined we re-use an old setup from a similar type of activity.

6. New Products - HSP timing file
Provides HSP timing to the resolution of the HSP integration time
File automatically generated when HSP data is archived
Files are posted on the UVIS team site at
It is a comma-delimited file
The format is described a top of each.file There is also a readme.txt file in the directory
Josh has developed S/W to process it

7. HSP Timing file
First measurement after first RTI0 since creation of the packet
First measurement in a packet (i.e in a record)
Time of the packet is xxxxxx.ddd (where xxxxxxx is the integer part of the SCLCK)
Time is xxxxxx /+ HSP integration time
UVIS TEAM MEETING 1/2006

8. HSP timing file
The HSP timing file provides the time at the start of each packet (xxxxxx.yyy) and the position within the packet of the first measurement after xxxxxx + 1 (xxxxxx is the integer part of the SCLK)
You can derive the time of each measurements in the packet knowing the integration time.
One packet = one DAPS record in DAPS file.

9. Notes on DAPS IDL routines
The accuracy of the SCLK to SCET conversion depends on which version of convert_sclk.pro is used.
Currently you should be running version 1.12 (which follows the latest version of the spacecraft clock conversion file - SCLKSCET.00095)
The convert_sclk.pro version number is at the top of the file ;

10. Notes on DAPS IDL routines
Josh has developed a new version of convert_sclk.pro that relies on the ICY DLM library and directly access your current spacecraft clock kernel (cas00095.tsc)
Under this solution you are responsible for updating the spacecraft clock kernel.
ICY DLM needs to be installed on your workstation or laptop.
