Operations / Software Comments - 02/18/04 TIDE Telecon

Operations:

Reminder:  A record of non-standard TIDE Operations is now kept current on the 
web.  You can get to the site by clicking on 'Ops' or 'Operations' on the TIDE 
home pages or by bookmarking 
http://satyr.msfc.nasa.gov/TIDE/tide_operations.html.  Note: only 2003 and 2004
are up-to-date.

There was another Polar GGS Telemetry Module (GTM) upset on 02/12/04 at 
03:04 UT.  TIDE did not come back up after the GTM reset so TIDE was also 
reset, the software patches reloaded, and high voltage ramped.  TIDE was backup
by 01:12 UT 02/13/04. 

Routine use of Science Mode 2 data started 01/28/04.  A schedule of the times 
when Polar switches between Science Mode 1 and 2 is available at 
http://pwg.gsfc.nasa.gov/polar_plan/plan.html.  Just click on 'Schedule of 
Science Mode Switching Times'.  Note:  The record length in the level-zero 
files is much larger in science mode 2 so from now on the level-zero files 
will be 104 mbytes per day.  As a result, more space is needed on the data 
archive at GSFC.

There is a Polar attitude adjustment scheduled for 03/01/04.  TIDE's high 
voltage will be shutdown at 14:00 UT.  The high voltage will be ramped at 
~21:00 on 03/04/04.


Development version of tide_lz_v5.8.0

Note:  The software will not be released or implemented on the web until the 
software has been verified.  We need your help in doing that.

In December Dick West implemented Phil Valek's software to estimate the polar 
angle distribution in the Stops data.  Basically he uses a gaussian fit of the 
spin curve to estimate the width of the polar angle in terms of bins (1-7).  
The flux is then simple divided by that number before moments are calculated.  
We still need to verify that the implementation is correct.  The flux 
correction is currently only available when calculating moments and velocity 
distribution.  Dick's initial results are in 
http://satyr.msfc.nasa.gov/tideteam/polar_angle/.  There is a spectrogram and 
moments and velocity distribution plots and files for four cases: one with no 
correction (standard filename), one with the correction done for each energy 
(ind in filename), one with the correction based on the average over energy for
a spin (avg), and one done for the sum over energy (sum).  We need times when 
Phil or Craig used the technique in order to verify the results.  We also need 
to know if the calculation should be done for each energy, the sum, the 
average, or whether it should be an option.

Dick has just finished implementing the mask correction option based on work 
done by Steve Christon.  Some preliminary results are in 
http://satyr.msfc.nasa.gov/tideteam/mask_corr/.  Initial results using Steve's 
software are in the test_software subdirectory.  Results using tide_lz_v5.8.0 
are in the prod_software subdirectory.

Dick has also finished implementing the initial version of the software that 
limits the moments spin angle integration limits to a user provided delta 
centered at the magnetic field.  The initial moments results are in 
http://satyr.msfc.nasa.gov/tideteam/bfld_trace/.  The user can select no limits
(_n.mom in filename), positive B-field (_p.mom), negative B-field (_m.mom), 
or both (_b.mom).  There is also a spectrogram plot.
