Decay Display - Measured vs Modeled
Use the Decay Plot - Measured vs Modeled option (Geosoft.uxo.gxnet.dll(Geosoft.GX.UXO.UxaDecayDisplayQc2;Run)*) from the AGC Expert User > Static Data Inversion menu to plot the measured and modeled decays of the coils from TEMTADS and MetalMapper.
Decay Display - Measured vs Modeled dialog options
Databases | |
Prefix | Select the databases prefix (e.g., SAM, SFR). Script Parameter: UXANALYZE.DD_DATA_PREFIX |
Target group | Select the target group from the target database. Script Parameter: UXANALYZE.TARGETGROUP |
Source group | Select the source group from the source database, which has been modelled using Batch Modelling. Script Parameter: UXANALYZE.SOURCEGROUP |
ID channel | Select the ID channel from the source database. Script Parameter: UXANALYZE.TARGETID |
Mask channel | Select the mask channel from the source database. Script Parameter: UXANALYZE.TARGETMASK |
Data To Display | |
Sensor channel | Pick the sensor channel from the list of channels in the survey database. Script Parameter:UXANALYZE._SENCHAN |
Low gate | Pick the low gate from the list of available gates. The list is from 0 to the number of gates for the selected sensor minus one. Script Parameter: UXANALYZE.LOGATE |
High gate | Pick the high gate from the list of available gates. The list is from 0 to the number of gates for the selected sensor minus one. Script Parameter: UXANALYZE.HIGATE |
Tx coil channel | Pick the transmitter channel from the list of channels in the survey database. Script Parameter:UXANALYZE.TXCOILCHANL |
Rx coil channel | Pick the receiver channel from the list of channels in the survey database. Script Parameter:UXANALYZE.RXCOILCHAN |
Dipole | For the modelled responses, select the dipole results to plot. Default value is 1. The maximum dipole available is determined by the number of dipoles selected when modelling the data (Model Targets - Batch Mode). Note: the dipole number is represented by the line version in the subset database. Please refer to Application Notes section of Model Targets - Batch Mode for more details. Script Parameter:UXANALYZE.DD_DIPOLE_SOLVER |
Decay Map | |
Target selection | Decay maps can be created in a Batch or Interactive mode. In Batch mode, the decay map is created for all the targets in the target database, whereas in Interactive mode, only the map associated with the selected target ID is created. Script Parameter:UXANALYZE.TARGET_SELECTION_METHOD |
ID | Select the target ID. This entry is enabled only in the Interactive mode. Script Parameter:UXANALYZE.TARGETIDSELECTED |
Map prefix | Map prefix is combined with the target IDs to create the decay map name: Prefix_target ID.map. Script Parameter: UXANALYZE.DD_MAP_PREFIX |
Map name | Map name is formed as: [PREFIX]_[GROUP].map, for MetalMapper [PREFIX]_[GROUP]_Tx[TXINDEX].map, for TEMTADS where [PREFIX] is the prefix entered in Prefix entry, [GROUP] is the subset database line/group name, and [TXINDEX] is the transmitter coil index retrieved from Tx coil channel. This field is read only. Script Parameter:N/A |
Data range | Data range determines the vertical extent of the plots.
Enter the range manually or use the
If left blank, the default values will be retrieved from the subset database. Min and max values should be greater than 0.001, as the plots have logarithmic axes.
Script Parameters: |
Chi2 threshold | Enter the Chi2 or correlation coefficient threshold. For each transmitter-receiver combination, if the correlation coefficient of the measured and modelled data is less than threshold, the graph is highlighted (yellow). Default value is blank. If the threshold is blank, no comparison is done. Script Parameters: UXANALYZE.DD_CORR_THRESHOLD |
Overlay background noise | If selected, the background noise will be overlaid on the output map. The background noise channel, UXA_Noise_Floor, is created when Level Advanced Sensor Data is executed. Selected by default. Script Parameter:UXANALYZE.DD_OVERLAY_BKG_NOISE |
Application Notes
To create decay curves plots that display different data (for example time gates or dipoles), enter different plot prefixes for each data combination.
The symbols used to plot the measured and modeled data can be reviewed and modified from uxa.config file located in the C:\Program Files\Geosoft\Desktop Applications \etc folder. To review or modify the file, open the file in a text editor, and look for <decayDisplayQc> tag. The elements <posSymbol>, <negSymbol>, and <connectingLine> are used for measured data, and <posSymbol2>, <negSymbol2>, and <connectingLine2> for modeled data.
*The GX tool will search in the "gx" folder. The GX.Net tools, however, are embedded in the Geosoft.uxo.gxnet.dll located in the bin folder. If running this GX interactively, bypassing the menu, first change the folder to point to the bin folder, then supply the GX.Net tool in the specified format.
