Estimated Total Execution Time (hours, including overheads)
General Description
This program intends to measure the rotation rates of young stars
in the Rho Ophiuchus dark cloud. The rotation rates are measured
by searching for PERIODIC photometric variability (caused by
starspots) in these stars. As such, the timing of OB execution
is the critical parameter for the success of this program.
Please read the Time Critical Aspects section for more information.

Critical Observing Condition Constraints
As execution of OBs at the correct time is of the highest priority
for this program, constraints are necessarily very relaxed. We
have no moon requirements, relaxed seeing constraints and require
only thin cloud coverage or better.
Time-Critical Aspects
Because of the need to detect and measure rotational periods for these
stars, THE TIMING OF OB EXECUTION IS CRITICAL. Our simulations show that the best
observing strategy is for 3 OBs to be executed every night, for 12 consecutive nights.
The spacing of these 3 OBs should be as close to evenly spaced as possible - we
would like 1 OB executed at the start of the night, one in the middle and one towards
the end of the night. Modest departures (i.e 1 hour or so) from this schedule are
acceptable to us.
If a single night of observations is missed, due to weather or other factors, WE
WOULD LIKE 6 EVENLY SPACED OBs TO BE EXECUTED THE FOLLOWING NIGHT. This will minimise
any aliassing problems in the resulting dataset.

Do all your OBs comply with the instrument-specific requirements listed
on the instrument-specific Phase 2 web page ?
If this is a pre-imaging run, did you select PRE-IMAGING for the Observing
Category for each Observing Template ?
Do all your finding charts comply with both the general and instrument-specific
Phase 2 Web Pages ?
If you submitted OBs for standard stars, did you specify the magnitude
and spectral type of all standard stars in the OBs ?
Have you included OBs for any calibrations that you need but which are
not part of the Calibration Plan ?
If you are observing Moving Targets, have you attached suitable ephemeris
files to your OBs?
If you have preferences which OBs should be executed first, did you make
use of the User Priority field in the OBs ?
If this is a run that requires coordinated observations with other facilities,
did you give proper instructions in the Time-Critical Aspects Section ?
Did you set 'New Preset' flag in all acquisition templates to 'True'?
Have all your submitted OBs the same filter for the acquisition template
and for the first science template?
Did you combine calibration templates with science templates for any
OB?
Did you combine imaging and spectroscopic templates for any OB?
Did you submit any Focus template?
