Integration Time Estimator for Position Switching Method Ver. 2.190718

The meaning of each parameter is explained at Time Estimator for Position Switching Observations.

  1. Receiver Single2-Beam(FOREST Beam1 and Beam3)
  2. Polarization (Default:Double)SingleDouble
  3. Tsys (K) @EL=70deg. (*)
  4. Trms (Ta*) (K) required
  5. Total number of different ON points (>1 for mapping; =1 for using 2-Beam)
  6. Integ. time of one scan (sec) (typically 20 sec, or shorter)
  7. Number of ONs per OFF (2-Beam: blank)
  8. Maximum Elevation of the Target(deg)
  9. Frequency (GHz)
  10. Resolution
    Frequency resolution (kHz)
    Velocity resolution (km/s)

(*) Recommendation: 150 K (FOREST 110GHz), 300K (FOREST 115GHz), 250 K (T70 72GHz), 150 K (T70 86GHz)

* Parameters :
1. Receiver = Single
2. Polarization = Double
3. Tsys_inp (K) = 
4. Trms (Ta*) (K) = 
5. Total num. of different ON points = 
6. Integ. time of one scan (sec) = 
7. Num. of ONs per OFF (2-Beam: blank)  = 
8. Max Elevation (deg) = 
9. Frequency (GHz) = 
10. Resolution
  - Frequency resolution (kHz) = 
    - Velocity resolution  (km/s) = 

* Results :
Scan number for one ON-point_sm = 
Tsys_obs_sm =  (K)
Total obs. time_sm  =  (min)
Total obs. time_sm  =  (hr)

Version = 2.190718

1. "Total obs. time" includes OFF integration and telescope sluing time, and NOT includes the overheads for pointing and tuning.
2. Scan number = (Beam number) * (Sequence number: on-off or on-on is one set), NOT includes polarization.
