If performing a scan map, enter the length of the map in the scan direction, and the width of the map (both in arcseconds): Length: Width:
Input below the current opacity values. If 450 Tau is unspecified, it will be derived from 850 Tau. If 850 Tau is unspecified, it will be derived from CSO Tau, as well as 450 Tau if needed. The same hierarchy applies to deriving opacities at 350 and 750 microns. All values must be >= 0
CSO Tau: Short Array Tau: Long Array Tau:
Average airmass of source during observation (>= 1):
If the calculator is being used to find the integration time required for a given sensitivity enter the desired levels below:
1-sigma rms (in mJy) to be reached (> 0) with Short Array: with Long Array: Note: If one of the sensitivities is left blank, the calculator will derive it, based on the integration time required to achieve the other sensitivity. When doing polarimetry, remember that this is the rms polarized flux.
If the calculator is being used to find what sensitivity may be achieved by a certain number of integrations, enter the number of integrations for the observation mode as specified above:
Number of Integrations:
