General Description

We want to observe an eclipsing binary system in NGC 6822 having K ~ 18.5
 mag
outside eclipses (e.g. close to both quadratures). For this reason two sets 
of OBs (N6822-Q1-N* and N6822-Q2-N* to observe our system close to the 
orbital phase of 0.75 and 0.25 respectively). Each OB should be executed on one
 of the 
nights listed in the ephemeris file appended to a given OB. In order to calibrate
 
our observations onto the standard system 5 standards from  UKIRT list 
were selected. One of our N6822* OBs should be executed on the photometric night
 together 
with those standards. We have specified N6822-Q1-N1 to observed under photometric
 conditions. 
However if during executing of N6822-Q2 OBs (e.g. on different nights) the conditions
 
are photometric and N6822-Q1-N1 is still not observed, please observe our set of
 standard stars 
together with a given N6822-Q2 OB. In such a case NGC6822-Q1-N1 OB could be executed
 under not 
photometric condition later on. (e.g. we do need just one N6822-* OB to be observed
 under 
photometric conditions together with the selected standard star OBs. It does not
 matter 
if this is N6822-Q1* or N6822-Q2). Since  both sets of N6822 OBs will be observed
 on different 
nights this information should improve the chances to calibrate our observations.
 
    
We would appreciate very much if some additional standards 
could be observed during twilights on the photometric night
(both NICMOS and UKIRT standard are usefull).

Special Execution Requirements

Our science N6822* OBs should be executed on different nights from the
 
appended lists, which are also given below. One of the OBs shoudl be executed togehter
 with 
selected standard stars (STD_FS*) - see general description.

OBs N6822-Q2-N* should be executed on some of the 
following nights
