The phase-lag distance to the carbon star CW Leo: part II

This DDT proposal is the .successor. to proposal DDT_mgroen01_6.In the original proposal we argued that it is possible to obtain aphaselag distance to the wellknown Carbon star CW Leo, and obtained2 epochs of SPIRE time.In this proposal we present first results and demonstrate that the method works and present a first distance estimate.The dominant error is in the phaselag, and we ask for 2 additional epochs to reduce this error, and obtain a more precise and accurate distance.
