Next: Writing Visibility FITS Files Up: Reading Visibility FITS Files Previous: AIPS Frequency Bugs . The time stored in a Miriad visibility dataset is nominally UT1 (although the difference between UT1 and UTC is not significant for the purposes of Miriad ). ... When a FITS file contains multiple antenna tables, the times stored in the FITS file have usually been offset from the true time by the AIPS task DBCON . Task fits assumes that such an offset has been added, and corrects for it. ...

... The 100-MHz passband recorded was centered at 1.665 GHz. ... Successive cross scans cycled through successive beams in the order Beams 0-6. ... Poln A = 3.04 arcmin (rms = 9 arcsec) . ... Poln A . ... There is some indication that the coma lobe levels may be a little higher for Poln B. It is of interest to compare the above values for SEFD (~4.3 and 5.7 Jy, for the orthogonal polarizations of Beam 0) with those from ALFA at 1.4 GHz (~2.75 Jy for Beam 0), and the L-Band Wide receiver (LBW; ~2.2 Jy). ...

... These values are functions of the geographical (geodesic) latitude and the height of the point above the sea level. ... The option also permits to solve the reverse problem — to calculate approximate values of observatory latitude and its height above the sea level depending on the introduced values of dxy and dz. ... It should be mentioned that low precision of dxy and dz for some observatories in the list maintained by MPC leads to negative value of height above the sea level for some of them. ...
