What are the pt files in the data directories?
The rpt files are summary report files generated after the data were transcribed from tape to disk. To ensure that the data tapes were read accurately, each data file was checked individually after it had been copied to disk. The summary report files were generated by analyzing the data files with a data format specific program to verify that the date, time and, if available, ship position information were within a legitimate range. The program also checked the date and time of the data files to verify that the data were in ascending time sequence. For data formats containing geophysical data, the summary report would also contain the appropriate minimum and maximum data value. The summary report files were named to correspond to the data file from which the summary information was generated. For example, t1105.rpt corresponds to data file t1105.dat.
