Heard "fire-ex ready" after the TOTO sensor hold. Not the best thing to hear 😐

Without a payload attached to the second stage, the Falcon 9 launch vehicle weighs 553,600 kilograms, contains 526,950 kilograms of propellant...
What is the source of these (quite precise) figures? Pre-densification, there was an Environmental Impact Report that quites the exact capacities, but as far as I know that was not updated. Also the empty mass of each stage has been the subject of much speculation. If we knew the sum exactly that would be very helpful.
So where did these figures come from?

Per L2 naughty "out of family" sensor that scrubbed the SpaceX Falcon 9 NROL-76 launch was a TOTO (Temperature Ox Tank Outlet) sensor. They had redundancy, but didn't want to risk losing another one, so the "abundance of caution" was as presented. Important to note, as some people see SpaceX as a bit "gung ho", they are as cautious as required, as proven.
24 hours is the current plan, but the access (depending which TOTO sensor on the first stage) for R&R will determine turnaround.

Updated launch weather forecast for tomorrow.
LCC wind limit for Falcon 9 is 30kts. So we're predicted to be under that for tomorrow, too.
