Okajima (GSFC)\n\nWe want to inform that the 14-inch Goddard Robotic Telescope (GRT) has been \nchasing the Swift pointings starting from December 24, 2012.  \nOur collected data are available at:\n\nhttp://asd.gsfc.nasa.gov/Takanori.Sakamoto/GRT/grt_swift_pointing.html\n\nDue to a combination of position of the Swift's pointing and weather at the site, \nabout maximum of 10% of the Swift's fields are simultaneously monitored by the telescope \n(GRT responds automatically via GCN SWIFT_POINTDIR notice).  To be complimentary \nwith the Swift NFI data (especially UVOT), GRT is collecting images in the R filter \n(fifteen 60-sec exposures for each pointing).  \n\nThe images are calibrated for bias, dark and flat.  Only the images with successfully \nassigned WCS information are available.  Since all the data acquisition, reduction and \nanalysis are performed automatically, some images might not be processed property (or \nmight be of a lower quality).  The processed images observed at the previous night will \nbe available on the above webpage around 16 UT that day.  \n\nIf you use GRT data for your publication, please reference the GRT paper: \nSakamoto et al. 2011, Advances in Space Research 47, 1444-1450\n\nWe are hoping that our additional optical images will be useful to the community \nto enhance the science outputs using the Swift data.",
