Meerkat (observatory)
MeerKAT clock corrections file
This file is distributed by the observatory. It records the local clock difference from (I think) GPS. It may cause some problems for TEMPO2 as it has a header line “# UTC(MK) UTC” when TEMPO2 would expect “# UTC(meerkat) UTC” or “# UTC(meerkat) UTC(GPS)”.
If questions arise, contact Ryan Shannon rshannon@swin.edu.au
