## Sensitivity estimation

Step #1: Initialization
  Initialize the values of , , , , , , , , , , , , , etc...
Step #2: User input
  Get the telescope time ( ), the number of sources ( ) and the elevation ( ). For mapping, get the map sizes. There are two cases:
  EKH restoration
    The following checks and computations must be done.

    |  |  | (29)
    |  |  | (30)
    |  |  | (31)
    |  |  | (32)

  Shift-and-add restoration
    The following checks and computations must be done.
    1. is set to the minimum of the empirical increasing function of because this restoration algorithm assumes that the restored sources are almost point-like.
    2. with .
    3. If , then

       |  |  | (33)
       |  |  | (34)
       |  |  | (35)

    4. Else

       |  |  | (36)
       |  |  | (37)
       |  |  | (38)

       We note that in this case, is not here a real number of source but more a number of submap: It does not need to be an integer.
Step #3: Computation of and

  |  |  | (39)
  |  |  | (40)

  If , then return the following error message: ``The telescope time must at least be .''
Step #4: Computation of , and
  OnOff

    |  |  | (41)
    |  |  | (42)

  Mapping

    |  |  | (43)
    |  |  | (44)
    |  |  | (45)
    |  |  | (46)

Step #5: Computation of , and

  |  |  | (47)
  |  |  | (48)
  |  |  | (49)

Step #6: Computation of (Mapping only)

  |  |  | (50)
  |  |  | (51)
  |  |  | (52)
  |  |  | (53)

Step #7: Computation of actual and (Mapping only)

  |  |  | (54)
  |  |  | (55)

Step #8: Computation of
  OnOff

    |  |  | (56)
    |  |  | (57)

  Mapping

    | (58)

Step #9: Computation of the actual , and
  We note that 1) the actual number of scan is when and when and 2) the true elapsed telescope time might be smaller than the user input.

  |  |  | (59)
  |  |  | (60)
  |  |  | (61)

The noise computation is done for three different values of (excellent, good and average conditions).
