Estimated Total Execution Time (hours, including overheads)

• 28.6h

General Description

• The purpose of this programme is to obtain circular spectropolarimetry
   of 6 variable peculiar stars at different epochs spread across Period 79 so as to
   determine their magnetic fields and to characterise their (periodic) variations.
   For each programme star, between 2 and 8 OBs have been submitted, which should be
   executed at epochs spread as evenly as possible over the semester. That is, for
   stars for which observations are required at 8 epochs, observations should take
   place approximately every 3 weeks; for the star for which observations are requested
   at only 2 epochs, one OB should be executed towards the beginning of the period
   and the other towards its end; etc. Exact time intervals between consecutive observations
   of the same star are unimportant, but too short intervals (less than 1 week), as
   well as the accumulation of a significant fraction of the observing epochs over
   a short fraction of the semester, should be avoided at any rate. For convenience,
   for each star, the OB names are of the form " epoch i of N", so that
   the observer can easily figure out the repetition rate of the observation of the
   considered target.

Waiver Requests

• 079.D-0240A.01.WAV; submitted Jan 8, 2007; granted Jan 8, 2007: non-std
   readout mode A,1x1,low

Critical Observing Condition Constraints

• In order to avoid possible saturation of part of the spectrum, the submitted
   OBs should only be executed in seeing *worse* than 0.6".

Time-Critical Aspects

• For each programme star, between 2 and 8 OBs have been submitted, which
   should be executed at epochs spread as evenly as possible over the semester. That
   is, for stars for which observations are required at 8 epochs, observations should
   take place approximately every 3 weeks; for the star for which observations are
   requested at only 2 epochs, one OB should be executed towards the beginning of the
   period and the other towards its end; etc. Exact time intervals between consecutive
   observations of the same star are unimportant, but too short intervals (less than
   1 week), as well as the accumulation of a significant fraction of the observing
   epochs over a short fraction of the semester, should be avoided at any rate. For
   convenience, for each star, the OB names are of the form " epoch
   i of N", so that the observer can easily figure out the repetition rate of the observation
   of the considered target.
