... Many Miriad tasks support on-the-fly selection and averaging of the channels to be processed. ... Channel-0' data (data formed by averaging all spectral channels together) are also treated as continuum data. ... For the spectral data, if the channel number does not correspond reasonably directly with velocity ( e.g. if Doppler tracking was not used), then it might be desirable to resample the spectral data at equal increments in velocity. ... channel . This gives raw or averaged spectral channels. ...

... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ... The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....

... The absolute magnitude of the RCBs in the LMC and the small number of Galactic RCBs implies that they are very rare stars. Together with statistics for related stars, the total number of hydrogen-deficient stars in the Galaxy is estimated to be about 1000 ([ Warner 1967 ]). Whilst the luminosity of RCBs is similar to that of other low-mass stars as they evolve rapidly from the asymptotic giant branch to become white dwarfs, their frequency is much lower. ...

Next: A modern two-channel Up: Sample instrument files Previous: A simple photometer . ... It has a ``neutral'' filter in addition to standard uvby filters. ... The positions of these two filter mechanisms are recorded as two adjacent digits in the data, so we can treat them as a single filter code; the second digit is 1 when the ``neutral'' filter is in the beam. There is also a shutter whose position is encoded separately in the data stream: 0 means open, 1 means shut. ...
