Adjusting a Chart to a new Time or Date

This section describes how to use a rectification-assisting tool to adjust the date, time or angles of a natal or event chart. (If the chart that you are displaying is not a natal or event type chart, then the Rectify button will be disabled.)

>> To adjust a chart

1.Display the chart that you wish to rectify in the "View Chart" window. (If you are viewing a multiwheel, then make sure that the chart you wish to rectify is the first charts listed, which is usually the innermost chart.)

2.Click on the Rectify button

3.This will display the "Rectify Assist" dialog box.

>> To adjust the chart’s date

•Click on the spin button next to the Date box to change the date by 1 day at a time, or type a new date directly into the box.

>> To adjust the chart’s time

•Click on the spin button next to the Time box to change the time by whatever interval is selected in the Time Step Interval box, or type a new time directly into the box. (You can make the Time Step Interval box visible by clicking on the More button.)

>> To adjust the chart’s MC or ASC

•Click on the spin button next to the MC or ASC box to change the angle by whatever interval is selected in the Angle Step Interval box, or type a new time directly into the box. (You can make the Angle Step Interval box visible by clicking on the More button.)

>> To adjust the chart’s latitude or longitude

1.Click on the More button to make the Lat and Long boxes visible.

2.Click on the spin button next to the Lat or Long box to change the angle by whatever interval is selected in the Angle Step Interval box, or type a new latitude or longitude into the box.

Whenever you adjust any of the values, then the data displayed in each of the other boxes is updated automatically to ensure inter-consistency between them. For example, adjusting the MC by 1 degree will cause the time to shift by 15 seconds.

Note that if spin buttons are used to pass the time forward through midnight, then the date is automatically incremented by one day. If the time passes backwards through midnight, then the date is automatically decremented by one day.

Angles can be entered in degrees, minutes and seconds (e.g. "133 24 20") or in zodiacal annotation (e.g. "13 Cn 24 20"). For more information on entering angles see Entering Angles.

Time can be entered in hours, minutes and seconds and include an am/pm indicator (e.g. "7:30" or "2:23pm"). See Entering a Time for more details.

>> To preview the effect of the changes on the chart image

•Click on the Apply button.

This will create a new calculated chart, and replace the chart image with an image using the new chart, but leave the “Rectify Assist” dialog box where it is for further adjustments to be made.

You can check the Transparent box to make this dialog semi-transparent. This allows you to see otherwise hidden parts of the chart when you are applying changes and leaving this dialog open.

>> To apply the changes and return to the View Chart screen

•Click on the OK button. This will create a new calculated chart, and replace the chart image with an image using the new chart, and The “Rectify Assist” dialog box will disappear.

You may repeat these procedures as many times as you wish with the same chart image. When you display the first adjusted image, a new chart is created. When subsequent adjustments are made, this new chart is edited, and no further new charts are created. Note that the new chart calculated this way will be unsaved (unless you have switched on the Autosave option), so you may wish to save it before proceeding by clicking on the Save button.
