Robson, E. I., Eve, W. D., Ade, Peter A. R., Rice, D. P., Clegg, P. E. and el Atawy, S. 1978. Submillimetre multicolour photometry of astronomical sources. Infrared Physics 18 (5-6) , pp. 781-790. 10.1016/0020-0891(78)90104-5

Full text not available from this repository.


Techniques and instrumentation for submillimeter photometry are discussed. The described photometer is designed to work over the wavelength range 2 mm to 300 microns and uses bandpass filters to isolate the windows at 1200, 850-750, and 450-350 microns. Information on atmospheric transmission for various amounts of water vapor is presented. The photometer uses aperture stops, selective filters, sky chopping, Fabry optics, and an inbuilt offset guider. Observation and calibration procedures are considered, and preliminary results for Rho Oph, Sgr B2, and W51 are reported.
