Recall that there are two versions of MIDL for the Cassini team - a test version and a regular version.

These changes apply to the regular version and the test version:

These changes apply only to the test version:

2005-09/29 - Multiple changes.

The strategy is to provide two versions of MIDL for the Cassini team - a test version and a regular version.
Both versions have been updated.
The test version has been updated substantially, and now requires Java 1.5 to run.

These are the changes to the regular version.

The test version of MIDL (which requires Java 1.5 to run) has the above updates, plus some additional changes:

2005-01-13 : Several Updates -

  1. Fixed a timing problem - was not correctly converting to UT from ET; there was a 64.184 sec lag in the data (the data was showing up too late)
  2. Changed the way time averaging is done in the particle line plots. In the past, the averaging intervals were dependent on the data points. The start of the first averaging interval would be at the time of the first data point. Then if there were gaps, the averaging intervals would then reset on the start time of the next data after the gap.

    Now the time bins are fixed according to the start time of the data window used for the plot. This mimics the way the time averaging is done in the spectrograms, and it allows a more direct comparison between the data in the spectrograms and the data in the line plots.

  3. LEMMS PHA data is now normalized with the singles rates (also just learned from Stefano that this might not be right - stay tuned)
  4. LEMMS calibrations used are very close to the latest from Stefano, but there are likely to be more changes soon. The PHA calibrations are now close, but the LEMMS E and F detectors still have some disagreements.
  5. PostScript orientation problem now fixed (has been fixed before, but not reported here).
  6. Spectrogram plot window can be resized and the spectrogram will be redrawn (has been available beofre, but not reported here).
  7. Fixed a problem in the spectrogram plot tool where the bottom row of flux would not show up sometimes.
  8. Fixed the spectrogram definition for the spectrograms which combine LEMMS PHA detectors E and F
  9. Added CHEMS accumulator rates to the tool; also added ability to look at all DPPS steps together
  10. Added ability to scale the axes in the MAG line plots

2004-08-10 : Two updates -

  1. LEMMS pitch angle plots are now available. The pitch angle is calculated on the fly using the MAG data in the spacecraft frame, and the calculated LEMMS look direction.
  2. In an effort to speed up the tool, MIDL now gets its Cassini data not from the Level 1A ascii files, but from binary files (which are created from the Level 1A files). This binary data is in the process of being examined by team scientists for correctness. This binary data is available from 2003, day of year 1, to 2004, day of year 218.

2003-11-14 : MIDL now moved outside the restricted area to limit the number of password prompts. You are now asked only once, and if you the select "remember" button, them MIDL will save this info on your computer so you never have to type it again.

2003-11-14 : LEMMS Priority channels now fixed. Still no LEMMS angle info for pitch angle plots

2003-11-14 : LEMMS now has settings (look under the list of instruments for the settings button) which allow the data to be shown as count rates, raw counts, etc. You can also choose the in-memory caching level.

2003-11-14 : Settings can now be saved. You can save the above LEMMS settings, and you can also choose a specific date to see initially (click the mission settings button under the list of missions on the top right)

2003-11-14 : ephem data not working yet... LEMMS Priority channels now fixed. Still no LEMMS angle info for pitch angle plots MIDL now moved outside the restricted area to limit the number of password prompts.
