UY Scuti should be fixed & Stephenson 2-18 to be removed until further notice

[Gregory]

Recently, UY Scuti had an analysis update by GAIA EDR3 using noiseless data.
It was found to be at a distance of roughly 1.8 kiloparsecs (~5,870.81 ly) from the Sun, which's much closer than previously thought, though no radius value regarding that was published.

Furthermore, Stephenson 2-18 has been given various results from different methods about its luminosity, with the first method calculating only 90,000 x the Sun's luminosity, while another method calculated it to be nearly 440,000 x the Sun's luminosity, leading to the 2,150 solar radius estimate, and another method calculated it to be 630,000 x the Sun's luminosity, which leads to another different radius value.

It's the same problem with NML Cygni as different measurements have given it highly various results of its luminosity calculations, including a value of 200,000, 270,000, and a parallax measurement from GAIA DR2 of 1.5259 +/- 0.5677 mas (milliarcseconds), all corresponding to radii values between 1,183, 1,640, and 2,770 solar radii.

Yet HV 888 also has too much uncertainty in its calculations.

With radius estimates as much as 762, 1,353, 1,374, 1,584, and 1,765 solar radii, the variations in the estimates is chaotic.


They should be replaced with Westerlund 1-26 and WOH G64 in an update, as those stars (despite WOH G64 being farther away) have been calculated by measurements with apparently better certainty and reliability until better measurements give us more-reliable calculations of UY Scuti and Stephenson 2-18.

Westerlund 1-26 and WOH G64 to be added to the bodies folder until future updates in US2.

Furthermore, measurements based on the multimessenger monitoring of supernovae estimated the radius of UY Scuti to be 909 times the Sun's radius, and its effective temperature to be 3,550 K and its luminosity at 124,000 times the Sun's.
