Release Notes mdi.vw_V:

The data in the DRMS series mdi.vw_V do not exactly match the data
that was contained in dsds.mdi__lev1_5__vw_V_06h. First of all, a
final platescale was calculated after the end of the MDI
mission. 

Secondly, the following known concerns exist:

1. Data that are present in the DRMS series dsds.mdi__lev1_5__vw_V_06h
   but that do not have a corresponding .rdb file in 
   ~soi/info/mdi_rec/lev1.5/vw_V_06h/*. However, these data do have a 
   corresponding .rdb file in ~soi/info/mdi_rec/lev1.8/vw_V_06h/*. These data are present in the series mdi.vw_V. The 
   list of data that fall into this category are in SECTION 1, appended.

2. Data that are present in the DRMS series dsds.mdi__lev1_8__vw_V_06h 
   and not present in the DRMS series dsds.mdi__lev1_5__vw_V_06h. These 
   data are not present in the series mdi.vw_V but could be if the data 
   were properly reprocessed. The list of data that fall into this category 
   are in SECTION 2, appended.

3. Differing source data: There are times for which the value of the FITS header keyword called "SOURCE"
   present in dsds.mdi__lev1_5__vw_V_06h do not match the value of the FITS header keyword called "SOURCE" in the
   .RDB files in /home/soi/info/mdi_rec/lev1.5/vw_V_06h/* for the
   corresponding 6-hour segment. These data are presenst in the series mdi.vw_V. The list of differing SOURCE keywords is
   SECTION 3, appended.
