GAL05 C2

Proposal

Proposal: GAL05:Drift-scan observations of the Cygnus cocoon
PI: Ievgen Vovk (vovk@icrr.u-tokyo.ac.jp)

Source information

This are just the name and coordinates of the central source. It is less relevant for the scheduling and observations.

  Source: LHAASO J2027+4119 

    RA (J2000): 306.9 deg 

    Dec (J2000): 41.33 deg 

Observational settings/limits

The scan can be performed at two time windows during the night (later this year only the second window is available since the first one will be before sunset). One window is before the culmination and one after. In the following the window 1 is the earlier of the two, window 2 the later.

Time window 1 before culmination:

Zenith [deg] = 20 

Az     [deg] = 45.7157 

Night Sky Background = Dark 

Wobbles = Fixed alt/az 

Time window 2 after culmination:

Zenith [deg] = 20 

Az     [deg] = 314.2844 

Night Sky Background = Dark 

Wobbles = Fixed alt/az 

Instructions for shifters

First of all please try to match the scheduled times as much as possible (e.g. schedule the source a few min ahead, so the data taking can start at the scheduled times). Please point at to the fixed Zd/Az position at the beginning of the scheduled time slot and stay there until the end of the scheduled slot. All the data can be taken in one run, there is not problem with the run being 1h long.

Depending on which window you have scheduled, please use the correct fixed Zd/Az configuration.
