Proposal

Proposal: EGAL06:Observations of galaxy clusters: Coma Cluster
PI: Mireia Nievas Rosillo (mnievas@iac.es)

Source information

  Source: ComaCluster-Center 
RA (J2000): 194.7752 deg
Dec (J2000): 27.6562 deg
  Source: ComaCluster-OFF1

  Source: ComaCluster-OFF2 
RA (J2000): 189.1283 deg
Dec (J2000): 27.6562 deg

Observational settings/limits

ComaCluster-Center, ComaCluster-OFF1, ComaCluster-OFF2
Min Zenith [deg] = 0 
Max Zenith [deg] = 50
Night Sky Background = Both
Wobbles = ON

Observational strategy

The strategy, each observing night (80 consecutive minutes [^1]), is as follow:

  • OFF-1 region for 20 minutes (1 run), during which the relative movement of the sky is 5 deg (AZ1, ZD1 → AZ2, ZD2)
  • ON region for 20+20 minutes (2 runs), during which the relative sky movement is 10 deg (AZ1, ZD1 → AZ2, ZD2 → AZ3, ZD3).
  • OFF-2 region for 20 minutes (1 run, AZ2, ZD2 → AZ3, ZD3).

[^1] take the data ideally with no interruptions, so that the AZ, ZD conditions in the OFF and ON match as intended. If for some reason there is some hardware problem and the 80 minutes need to get significantly reduced, an alternative (40 minute, half the observing slot) slot could look like either:

- Option A: 1 run in OFF-1 + 1 run on ON - Option B: 1 run in ON + 1 run in OFF-2.

Instructions for shifters

Observations in ON mode. Please report any hotspot in RTA / skymaps.
