... AstroCC is a coordinate conversion utility for astronomy. It accepts an object designation or the coordinates of an object and calculates coordinates in alternative systems, and at different dates, times, and locations. It also provides lunar and bright planet coordinates to aid in planning observations. ... BJD values may also be retrieved from http://astroutils.astronomy.ohio-state.edu/time/utc2bjd.html which is based on Eastman et al. ... Coordinate data are obtained from SIMBAD. ...

... O b jec tive To explain the process used to choose the lenses for the MROI delay line beam expanders. ... That the expanders introduce no more than 0.05 of RMS wavefront error to an initially perfectly collimated beam; 6. ... The mounting scheme we have designed for the beam expander lenses uses the surface of the lenses to register them in the optical tube assembly and we expect this to mitigate to a large extent the lens fabrication errors we have described above (see right hand panel of figure 2)...

... ARC 3.5m | NICFPS . ... Taking Exposures . ... As with other IR detectors, it has the capability to be read out non-destructively, allowing for multiple readouts per exposure. In NICFPS, the number of times the detector is read out for each exposure is determined by the Fowler Sampling (FS or NFS, Number of Fowler Samples) setting. ... The NFS=0 mode is somewhat unusual for an IR detector; in this mode, the array is reset, the specified exposure time elapses, and then the detector is read out. ...
