 The Portal aspect of the Rubin Science Platform lends itself well to extracting and plotting a light curve of an object with known coordinates.
 It can be accessed by clicking on the "Portal" panel on the main landing page at data.lsst.cloud.
+This example uses the "UI Assisted" means (selected by pressing the "UI Assisted" button on the upper right).
 
 Plotting of a light curve requires a data table which contains the observation time.
-For the simulated DP0.2 data, such table is the dp02_dc2_catalogs.DiaSource.
-This table can be accessed by selecting ``DP0.2 Catalogs`` tab on the left-hand side, and the ``dp02_dc2_catalogs.DiaSource`` tab on the right.
-This example uses the "UI Assisted" means (selected by pressing the "UI Assisted" button on the upper right).
+For the simulated DP0.2 data, such table is the dp02_dc2_catalogs.DiaSource, but it contains fluxes at times when the object was detected at ``SNR > 5``.
+This table can be accessed by selecting ``DP0.2 Catalogs`` tab on the left-hand side, and the `dp02_dc2_catalogs.DiaSource`` tab on the right.
 
-An example here considers a low-redshift SNIa (67.4579, -44.0802) and will extract the flux data from that location only when the object was detected at ``SNR > 5``.
-Such flux is derived from the processed visit image (PVI; “direct” image), ``psfFlux``.
 If the flux of the object at epochs when the ``SNR < 5`` is needed, a different table using forced photometry (``ForcedSourceOnDiaObject``) needs to be used and this is covered in another "HowTo" bit.

 Selecting the data for the object of interest will require entering the object coordinates in the "Spatial" constraints on the left, selecting the "Cone shape" button and a 2 arcseconds radius.
 The box next to "Temporal" needs to be uncheckd (allowing the display of all data points at the required RA and Dec).
