Special Remarks:
This is a monitoring programme. NOTE: non-standard read-out!

Abstract for MTS:
This is an ongoing long-term imaging FORS2 program to monitor the orbital motions of Eps Indi Ba,Bb. The target coordinate is an empty point in the sky, roughly where Eps Indi B will be in late 2007, halfway through a five year monitoring campaign.
TIME CRITICAL ASPECT: Four epochs of observations are needed in P76, spaced by ~1 month between Oct-Jan when the source is observable.
SPECIAL CALIBRATIONS NOTE:
The SR mode of FORS2 used with the 200kHz,1x1 read-out mode (a waiver has been granted). Twilight flats in the I-band are required in the FORS2 SR/200kHz,1x1 read-out mode.

NOTE added on 2.1.2006.: Airmass constraint relaxed following the input from the PI: The arimass constraints are completely unimportant. The seeing is important: the goal is to resolve the binary which is presently about 0.9 arcsec in separation (it will get smaller in the coming year). Rather than skipping the observation in January the epoch 4 which will be observed at HIGH airmass, can be done with seeing up to MAX 0.8".
