Inspecting Automatic Calibration Results

Automatic calibrations are those described in the operating manual, section 4.3, 4.4 and 4.5 (Gain, Noise, Tip Curve). These calibrations are performed automatically by the radiometer following the calibration settings in the measurement definition file (see section 5.8). Monitoring of automatic calibrations is carried out by the (enabled) Radiometer Status window on the main screen. The corresponding log file is CAL.LOG located in MY_DIRECTORY\RPG-HATPRO\.
In the Gain Calibrations group box only gain parameters are displayed (the only parameter that is adjusted by this calibration type, see section 4.4) while also Tsys (Tsys) and Tn (Tnoise) are selectable in Noise Calibrations and Sky Tipping Calibrations. The user may zoom into the data by clicking on the graphics display (holding the left mouse button pressed) and dragging the mouse cursor to a second position. When the mouse button is released, the zoomed data window appears. Zoom Out reverts to the previous zoom display. The precise moment of each calibration is indicated by a dot ( and  toggle this feature). All diagrams are synchronized if Synchronize Diagrams is active. Then zooming and zooming out is performed on all displays so that a common time axis is maintained. Independent Diagrams switches back to the non-synchronized display mode.
Below the Sky Tipping Calibrations data display the successful calibrations are marked by a green bar while failed calibrations are marked in red. By clicking on one of these bars the tip curve calibration details are listed and a graphical display of the sky dip is shown.
