A.1 ACS Example
The ACS WFC channel is used to observe a target at declination +35. The requested exposures are listed in Table A.1.
According to Table 6.1, there are 55 minutes of orbital visibility per orbit.
Therefore, a preliminary observing strategy can be created by the user to fit the observations in two orbits, as shown in Table A.3.
Table A.1:
Dither pattern (see Section 5.4) with an offset of 25" between positions
Table A.2:
Table A.3:
