'Deep imaging in Chamaeleon I'

Allocated time: 1h

The programme consists of four (4) pointings in Cham I, two each
in regions denoted as 'north' and 'south'. Four finding charts
are attached. The coordinates of the four pointings are:

'south' 1/2 (FC file 1/4)   11:07:33 -77:40:15
'south' 2/2 (FC file 2/4)   11:07:47 -77:32:30
'north' 1/2 (FC file 3/4)   11:10:22 -76:39:00
'north' 2/2 (FC file 4/4)   11:09:16 -76:31:20

The initial pointing precision is very relaxed due to the large
jitter width. Hence, the initial UT pointing should be fine.

Each of the four pointings should be observered in one OB 
with the following paramters:

(1) Simple preset, shortest DIT (brightest stars in all fields 
    have K = 6.0 - 7.x mag)

(2) Science observation:
    + AutoJitter pattern
    + DIT: 2s
    + NDIT: 15
    + NEXP: 1
    + NOFFSET: 25
    + JITTER.WIDTH: 60
    + Filter: Ks

The short DIT was chosen to cope with the saturation of the 
brightest sources. The short DITxNDIT and the high number of
offset positions was chosen to minimize the problem of detector 
remnants (afterglow at bright sources). A maximal jitter width 
(field coverage) is desired to maximize the covered area. 

If allowable by the time constraints, please feel free to shorten 
the number of DITs (NDIT) and increase the number of offset positions 
at constant total exposure time. This will increase the overheads 
but will further minimize the impact of afterglow contamination around 
the brightest sources.
