Thank you for sending the measurements table and resulting data subset file. From those files I can tell that only the HJD_MOBS column is blank. The FJD_UTC column is there in place of the JD_UTC column since it is not the left-most column, and it contains the fractional part of the JD_UTC values in the output table. HJD_MOBS values are blank because the values are all NaNs in the measurements table. Did you extract HJD_MOBS from the headers or calculate it using the "Add Data" module of Multi-Plot? If so, something possibly went wrong in the extraction. If you can't track down why the values are NaNs in the table, let us know. Once tracked down, I think the HJD_MOBS values should be written out correctly. Of course handling the JD_UTC values correctly in a non-leftmost column will require a new option setting. We'll look at adding that capability, but it may take a bit of time for it to bubble up in priority.
