Saving input data

Using Stuffit, the raw input data set is compressed and saved. Each input data set is on the order of 30 MB (22 MB when compressed). Long term archiving is best on CDs (650 MB per CD => 30 input data sets per CD)

tilt images:	***.EUP, ***.SUP, ***.WUP, ***.NUP (for East up, South up, West up, North up, respectively)
