Someone could add an approximation range syntax if they derived their own fuzzy dates specification. I've been considering the problem of fuzzy dates for a project idea. Maybe something like "..<" could join the first and last days of an approximate range, like "156X..<1585-12-25", which would be equivalent to "156X..1584-12-25", to say anywhere from 1560 to 1584. Depending how much information you want to encode you can imagine other extensions like showing the most confident guess. At that point it would be simpler to create tables to encode the available information.
I work 7-hour days, but I might work 2 or 3 hours during that time. A lot of the time I find the work unbearable and can only bring myself to do it in short intervals. When the task is interesting, involves my skills, and I'm making progress, I can work for hours with almost no breaks. It really is an emotional thing. I won't force myself to do anything that is really painful because it ruins my mood for the whole day. At the same time I feel guilty of days I get little or nothing done and I feel trapped by the time constraint of the work day, even though I work from home. I would really like to make a deal where I work independent of a work day, with no set hours and no expectations, and not feel like I'm on call all day, so I can do things other than work through the day and not feel like I'm cheating.
Approximation for the ASKAP images with help from Wolfram Alpha, .83 spheres is 10.4 steradians, so 903*70 billion is 63.21 trillion pixels, at ~1.65e-13 steradians/pixel, though there may be overlap in the images, unsure.
Approximation for HUDF is 38.44 million pixels, covering 11 square arcminutes (from Wikipedia) which is 9.308e-7 steradians at ~2.75e-14 steradians/pixels, so the HUDF is about an order of magnitude higher resolution.
