<br><font size=3>The form offers four different sections, labeled as: </font>
<br><font size=3>• ”XMM-Newton Revolution” </font>
<br><font size=3>• ”Absolute Time (UT)” </font>
<br><font size=3>• ”Phase” </font>
<br><font size=3>• ”Comments” </font>
<br><font size=3>The first three sections are exclusive. This means that
you can fill in only one section at a time depending on the kind of time
constraint you want to use. Inputs can be made either in the ”Earliest
Revolution” and ”Latest Revolution” input fields (where relative times
are required) or the ”Earliest Start Time” and ”Latest Start Time”
input fields (where absolute times are required). The allowed input range
for both is given in the documentation for the current AO. Input values
for ”Latest Revolution” have to be equal or greater than ”Earliest Revolution”.
Input values for ”Latest Start Time” have to be equal or greater than
values of ”Earliest Start Time” plus one hour. A specified range can
also be left open at the minimum or maximum side or both (to allow for
non-fixed repetitions) using the ”Any” button. </font>
<br><font size=3>There is also the possibility of repeating an observation,
specifying the number of repetitions Repeat x ”times” (0-98), the period
every x ”orbits/days”(1-999 rev., 0.42-999.99 days) and the ”tolerance”
(1-998 rev., 0.04-period days). For the special case of observations related
to orbital phases the third section of the ”Time Constraints” page offers
additionally the possibility of specifying the ”Reference time for Phase0”
in UT format YYYY.MM.DD.HH.MM.SS, the ”Period” (0.4200-366) in days,
the ”Phase” requested, and finally the ”tolerance” in days.</font>
