Free Air Anomaly data
From Steve May's 2/10/94 memo:
After extensive analysis of cross-ties within the '93 gravity data and
  with gravity data from other cruises (P192AR, P188AR, and L977AR)
  I have come up with the correction scheme given below.  It should be noted,
  however, that although this makes the data "usable", it is not of the
  accuracy of the above mentioned cruises.  In general, I estimate this data
  to have an accuracy of +/- 5 mgals.
Correction scheme:
1) Delete data between the following times:
   2310200 to 2311830
   2371000 to 2382330
   2432230 to 2440115
2) Static shift all data from 2301931 to 2432330 by -16 mgals.
   (A power outage at 2432330 appears to be responsible for this "tear".)
3) Apply a linear drift correction to the entire data set
   using the following end points:
     2301931 added -16 mgals
     2582330 added +10 mgals
