The SCUBA-2 Integration Time Calculator (ITC) – is web-based tool for calculating required integration times for SCUBA-2 observations. The Integration Time Calculator can be accessed via the following links:

- Time required for target RMS
- In this mode you can enter your desired sensitivity (1
*σ*RMS in mJy/beam) and the wavelength. The calculator will estimate the time required to reach this sensitivity and will also show the sensitivity which would be reached in this time at SCUBA-2’s other wavelength.

- In this mode you can enter your desired sensitivity (1
- RMS expected in given time
- In this mode you can enter the total observing time in hours. The calculator will estimate the sensitivity which would be achieved in each of SCUBA-2’s wavelengths.
