This program monitors a field in the open cluster NGC6475. The scientific
objective of the project is the determination of photometric rotation
periods of low-mass cluster members.

The herewith defined observations supplement a larger program that will
be executed in Max Planck time, which starts at the 5th of August.
They will extend the time baseline to register slow rotators. Therefore,
it is indispensable that the OBs for this program will be executed either
in the 7 nights before the Max Planck time (OBs NGC6475_1 to _7, ZERO_NGC6475)
or in the 10 service nights (8th Sep - 17th Sep) after the Max Planck time
(NGC6475_8 to _14), as indicated in the 'Time Interval' of the OBs. The
observations should be distributed uniformly over these time windows,
to ensure uniform sampling. No more than two OBs in one night should be
executed.

For more details about time critical aspects see README file.

One OB (ZERO_NGC6475) is used to calibrate the field photometrically
and should be observed in the photometrical night and be supported with
PCa.
