Update ephemeris for ASASSN-14ix (regarding Bruch's paper) In relation to: https://arxiv.org/pdf/2308.16106.pdf

The only available information consists of informal communications (Hambsch 2014a,b) reporting deep eclipses and an orbital period of 0.1444610954(1) d

The formal accuracy of this value must be grossly overestimated. It would lead to an error of eclipse epochs of merely 2.2 sec over a time base of 100 years!

I updated the ephemeris using the same data (not using TESS). Min(BJD) = 2457008.54251(3) + 0.144461097(4) E The value posted to vsnet-alert was a result of quick analysis (not involving a sufficient number of iterations), but was not "grossly overestimated". The MCMC chain is well-mixed and there is no anomaly in the posterior probability. The author needs to know that the error can be much smaller than one would assume naively or smaller than the exposure time, particularly in eclipsing systems with rapid ingress and egress, and if long-baseline collective data are analyzed. It is also not apparent in this paper who was responsible for the accuracy of this value.
