"In 2007, the Lunar Orbiter Image Recovery Project (LOIRP) began a process to convert the Lunar Orbiter Images directly from the original analog video recordings of the spacecraft data to digital image format, a change which provided vastly improved resolution over the original images released in the 1960s. The first of these restored images were released in late 2008."

  35. 35. 1 thru 4 are spread sheet tests, using actual data from runs. 5 is a record for a test in the image processing code, using the first synchronization bucket on this data set. Note the similarity to 4. The reason for the false signal before actual detection is the presence of a fiduciary marker in the data. Friday, June 12, 2009
