rdvinv
Module Version
0.6 23 IV 2010
General Description
rdvinv performs an OLA inversion on a set of ring-fit parameters Ux and Uy
for transverse velocity functions of depth
Status
This version has been superseded by Version 0.7
Included in JSOC release 5.9.
Never used for ring-diagram pipelines
This version supersedes Version 0.5
The source code and Makefile are in the JSOC CVS repository

Changes from Previous Version
Added logic for specifying input grouping of data set records by Carrington
Rotation, CM Longitude, Longitude, and/or Latitude
Output to multiple files named by lat and lon in segment directory
Bugs in current version:
The names of the output data files are misleading, to say the least;
specifically, the labels E and W for longitudes are reversed from what
they should be (longitudes labeled E are on the western, receding side
of the disc).
If the input data are not in a drms series, an output series cannot be
created — module will exit with an error message.
Arguments car, lat, and lon are not currently used.
When writing output to a file, rather than a drms record set, only one
set of files can be specified — if the input data set contains more
than one record, each inversion will overwrite the last.
