Sensitivity and mapping speed.

It is projected that Bolocam will be commissioned on the CSO in the Spring of 2000. A second camera is going to be used on the future LMT/GTM 50 meter telescope. This Section compares between the expected performances of Bolocam on the CSO and Bolocam on the LMT/GTM.

On the CSO, Bolocam will cover an 8 arcminutes field of view at$\lambda$ = 1.1, 1.4 and 2.1 mm. At 1.4 mm we expect to have a sensitivity of 35 mJy/$\sqrt{Hz}$. Bolocam on the CSO will have a relative mapping speed³ of $\sim$ 150. This mapping speed is two order of magnitude bigger than the mapping speed of SCUBA on the JCMT ($\sim$ 0.9 ) or MPIfR on the IRAM ($\sim$ 1). On the LMT/GTM telescope is expected to have a sensitivity of about 2 mJy/$\sqrt{Hz}$. The resolution will be about 6 arcsec and a field of view of 100 arsec in diameter. This data will produce a mapping speed of about 1800.
