Estimated Total Execution Time (hours, including overheads)
General Description
The aim of this proposal is to obtain full orbital phase coverage of the
X-ray binary Cen X-4, which has an orbital period of 15.1 hrs. The proposal was
alloacted 15hrs in SM mode with VLT+UVES. I was aiming for about 14hr on Cen X-4
(covering 0.93 orbital phases) and about 1 hr on flux standards and spectral type
templates (as mentioned in the proposal).
In my proposal I asked for two observing blocks of 9 and 5 hrs on consecutive nights
(observing the same object, Cen X-4). This is so that I cover all orbital phases,
without repeating the same phases. The observations should be taken within a the
same orbital cycle give or take a couple.
Ideally I'd like the the 9hr and 5hr blocks to be executed continuusly on consecutive
nights, but in order to be more flexible and after the suggestions from usd-help,
I have been granted the OK to use OBs for 2hrs, with a total of 7 (making up 14
hrs). If conditions are poor, then these can be split across a few nights, but not
too many.

Below is a table that may help u make sure I do not repeat the same orbital phases,
if the 9hr and 5hr blocks are split up. The table gives the orbital phase for different
UTs, from mid April to mid June.
The ephemeris used is HJD = 2451660.6432 + N x 0.6290522 days
