Next: The hardware and software Up: Keeping Time Previous: Keeping Time . ... Since the Earth is round, noon happens at different times in different places. This leads to the concept of local time . ... As soon as you need to communicate with distant places, you'll notice the need for a common time. ... Each local time is called a time zone. ... Other countries do not do this. ... In the US and some other countries, the local time zones have a name and a three letter abbreviation. ...

... These Frontier Fields will combine the power of HST with the natural gravitational telescopes of high-magnification clusters of galaxies. ... We are soliciting gravitational lensing maps for the last four Hubble Frontier Fields clusters (MACSJ0717.5+3745, MACSJ1149.5+2223, AbellS1063, and Abell 370) based upon the exceptionally deep HST FF imaging and other new ancillary data. ... For the full set of proposal instructions and requirements, see the FY16 Frontier Fields Lensing Map Call for Proposals....

... In the calibrated events lists generated by the pipeline, the events found to be on a bad pixel have already been removed. ... But epchain and emchain allow to generate events lists in which all events flagged for rejection (including those on a bad pixel) are still present. In that case the bad pixel flagging is reversible. ... The overwrite =Y option may be used to replace the existing bad pixels with the new ones instead of adding the new bad pixels to the old ones. ...

Modern AstroStatistics has emerged as a new field in recent times, informed by a Bayesian foundation, utilizing powerful computational tools like MCMC, and applied to diverse analysis and inference problems in Astronomy. ... The goal of our Special Session is to review current practices, highlight modern techniques, and explore how the transition into the realm of Big Data Astronomy can be facilitated. ...
