Hi Christophe,
I think you have figured out the "Page Rel" issue, but I'll give a little explanation here. The "Page Rel" option should only be used if you are plotting data such as airmass, tot_C_cnts, etc, if you only care about the shape of the curve, and not the exact data values. The "Page Rel" options forces the selected dataset to appear on the plot page without you having to figure out the scaling and shifting by hand. In this mode, the "Scale" value specifies the percent of the page to fit the plotted data on and the "Shift" value specifies the percent of the page to shift the plotted data. The "Shift" value will normally be between 50% (top of plot page) and - 50% (bottom of plot page). As you have figure out already, "Page Rel" should be disabled to plot typical data so that the plotted values correspond to the axis values (after making the scale and shift adjustments specified for that dataset).
I you have a detrended light curve plotted, click the "New Col" icon (
) on the left-hand side of the plot controls corresponding to the plotted data to save it to the table. you still need to save the
new table if you want to keep the table with the new columns added for future reference. Since AIJ updates plots in real time when changing settings, it is too slow to update the table every time a change is made, so you have to specify when to the save the
plotted data (e.g. after detrending, etc.) by clicking the icon and specifying the new column name(s). It would also pollute the table with a lot undesired new data columns if I attempted to add all versions of plotted data.
If I have missed answering another question or if the above does not help, please let me know.
