INTRODUCTION

     This file contains an accumulation of errors, changes, and notes for the
LRO Radio Science Raw Data Archive that were noted post launch, and date 
through the present.  The most recent entries are listed first.

RELEASE NUMBER: 6
RELEASE DATE: 2013-06-15
DATA COVERAGE: 2009-06-18 to 2012-06-09 (entire mission through 2012-06-09)

The fifth release of the raw navigation and ancilliary data sets contains 
data from LRO_SM_21 to LRO_ES_06.

The following datasets are incremented from the previous release:
TRK (tracking) and WEA (weather).  SFF (small forces - thruster) data
are not incremented from the previous release as no additional data exist in
this archive period.  The SPK data are not revised or augmented for this 
release.

The following WEA data files have end-of-year date roll-over errors.  The
errors have been fixed in the detached labels, but persist in the data files
themselves:
DATA/WEA/LRO_NO_04/2009365/USPS_2009365_1248.WEA
DATA/WEA/LRO_SM_04/2010365/USPS_2010365_0138.WEA
DATA/WEA/LRO_SM_04/2010365/USPS_2010365_2335.WEA
DATA/WEA/LRO_SM_18/2011365/USPS_2011365_0808.WEA

RANGE (laser ranging normal point) data are incremented through LRO_ES_06, 
with an exception of the following files from LRO_SM_26 which will be 
finalized and archived at a later date:
DATA/LRO_SM_26/7015_201209101224
DATA/LRO_SM_26/7015_201209101421
DATA/LRO_SM_26/7015_201209111228
DATA/LRO_SM_26/7015_201209111415
DATA/LRO_SM_26/7015_201209131147

The LOLA Science Team will continually update the Radio Science dataset on a
best efforts basis.

RELEASE NUMBER: 5
RELEASE DATE: 2012-12-15
DATA COVERAGE: 2009-06-18 to 2012-06-09 (entire mission through 2012-06-09)

This fifth release of the raw navigation and ancilliary data sets contains 
data from LRO_SM_06 to LRO_SM_23.

The following datasets are incremented from the previous release:
TRK (tracking) and WEA (weather).  SFF (small forces - thruster) data
are incremented from the previous release through 2011-12-11, when the last 
FDF25 files were generated.

The SPK data are not revised or augmented for this release.  

RANGE (laser ranging normal point) data are incremented through LRO_SM_21, 
and the entire past delivery is revised to reflect an improvement in 
processing algorithms. SFF (small forces - thruster) data are incremented from 
the previous release through 2011-12-11, when the last FDF25 files were 
generated.

The LOLA Science Team will continually update the Radio Science dataset on a
best efforts basis.

RELEASE NUMBER: 4
RELEASE DATE: 2012-03-15
DATA COVERAGE: 2009-06-18 to 2011-11-14 (entire mission through 2011-11-14)
This fourth release of the raw navigation and ancilliary data sets contains 
data from LRO_SM_14 to LRO_SM_17 as an increment to the previous release.

While the WEA, TRK and SFF data are raw, the SPK and RANGE datasets are 
processed.

The SPK data are brought up to date since Release 1, which contained orbit 
solutions through LRO_NO_13.  Seventeen new orbit solutions, for the Science 
Mission phases, have been calculated by the LOLA Precision Orbit team, and
are published here.

The RANGE dataset is not just incrementally updated through LRO_SM_17, but 
the entire previously delivered data set is resubmitted due to a revision 
in the calculating algorithm.

This dataset is produced and maintained by the LOLA Science Team on a best
efforts basis. 

RELEASE NUMBER: 3
RELEASE DATE: 2011-12-15
DATA COVERAGE: 2009-06-18 to 2011-09-06 (entire mission through 2011-09-06)

This third release of the raw navigation and ancilliary data sets contains 
data from LRO_SM_06 to LRO_SM_13 as an increment to the previous release.
It additionally contains a revision to the entire RANGE dataset due to
recalculation using a revised algorithm.

The LOLA Science Team will continue to update the Radio Science dataset on a
best efforts basis.  Please note that for this release, the RANGE, SFF, WEA,
and TRK data sets are brought up to date, while the SPK files remain 
unchanged since Release 1.

RELEASE NUMBER: 2
RELEASE DATE: 2011-06-15
DATA COVERAGE: 2009-06-18 to 2011-01-31 (entire mission through 2011-01-31)

This second release of the raw navigation and ancilliary data sets contains 
data from LRO_SM_01 to LRO_SM_05 as an increment to the previous release, 
which was of the mission from LRO_CO through LRO_NO_13.  This data release 
is approximately 3 months behind the LOLA data release schedule.  The 
LOLA Science Team will continue to update the Radio Science dataset on a
best efforts basis.  Please note that for this release, the RANGE, SFF, WEA,
and TRK data sets are brought up to date, while the SPK files remain static
as of the previous release.  An update through LRO_SM_05 for the SPKs is 
expected at the 9/15/2011 data release.

RELEASE NUMBER: 1
RELEASE DATE: 2010-12-15
DATA COVERAGE: 2009-06-18 to 2010-09-16 (entire mission through 2010-09-16)

This first release of the raw navigation and ancilliary data sets contains 
data from launch through 09/16/2010.  This dataset is accumulating, and 
will be updated on a quarterly basis.
