(D. Band 4/6/07) I am not sure which name is older. I have not strong feelings one way or the other.
(J. Chiang 4/23/07) Unless there is a good reason to change it to 'LAT_POINTING_HIST', I recommend that we change the documentation to use 'SC_DATA'. I recall having exchanges/conversations agreeing to change it from the obscure 'Ext1' to 'SC_DATA'. I do not recall similar exchanges regarding any change to 'LAT_POINTING_HIST'.
