Point Time-Series File

A point time-series file (PTSF) has a much simpler structure than a DTSF. It includes a single header record with an integer code (one four-byte word) describing the contents. If CODE = 2, then the values stored are water-surface elevations, and if CODE = 4, the values stored are flow rates. The subsequent records in the file contain the modified Julian time and the flow or water-surface elevation at that time. The first record contains four bytes of information and all subsequent records contain 12: eight bytes for the modified Julian time and four bytes for the flow rate or elevation. Linear interpolation is applied between consecutive values in a PTSF. No restriction is placed on the time interval between values. The user must ensure that linear interpolation is reasonable.
