Although one can rely on known fluxes of strong calibrators such as 3C273 and 3C111, their actual flux varies with time and you will need to depend on what CARMA, or other observatories, have supplied for you. The best method is to add a planet for bootstrapping the flux of your flux calibrator, at least if a planet in available during your observation. An alternative way is to use a planet, if available, in your observation and bootstrap its flux to scale the flux of your phase or amplitude calibrator. 6.9
During commissioning CARMA maintained a list of 12 ``secondary flux calibrators''6.10and publishes their fluxes as function of time. The current list is 4 (3C84, 3C273, 3C345, and MWC349) for which - based on 1mm and 3mm - also a spectral index is recorded if a reliable planet is available. Fluxes are maintained in MIRIAD in a database that you can consult using the calflux program:

This calibration list consists of the older BIMA flux calibrator list (1985-2002), appended with new CARMA values. There is a gap between November 2002 and December 2006, which includes the time the BIMA dishes were moved from Hat Creek to Cedar Flat for the CARMA merge.
Another source of information is the flux data maintained by ATCA6.11 and SMA6.12.
xplore is a tool outside of miriad that also contains time-flux tables for each source based on the same table.
