Hi - this might also be a 'software' post as well.
Sometimes, when I submit an observation of a slowly-varying star with a 'true' JD of (say) xxxxxxx.47 this will be rounded up at this end to xxxxxxx.5 - but if the exact time of xxxxxxx.5 has not yet been reached the observation is rejected by the usual 'observation must be between such-and-such a time and now' alert box. Is there any way around this, other than by providing needless accuracy for a 'red' observation?
This 0.03 day difference (0.47 vs 0.5 Day) amounts to 43 minutes of time error. I know this is a slowly varying star, but this sounds excessive to me. This error can be substantially reduced for "Free".
