Explanatory table

"Time" list |
List of all times with measurements; ticking the box next to the time selects the corresponding observation; by default, time is measured in days |

"Time step" list |
List of times for which pumping rate is changing in step-function. This list applies to “drawdown-pumping rate” plots for interpretation of pumping tests with variable rates by the straight line method |

"Power" text box |
Specifies the power index for time-drawdown (s - tn) plots. ANSDIMAT uses the inverse of the specified number n as a power to time. For instance, n=2 corresponds to the square root of t. The default value is n = 1 |

"Dimension" list box |
Selects the time units (day, hour, minute, second). ANSDIMAT displays time in the chosen units |
