General Description

We want to obtain an angular diameter for TX Psc, mostly in the
continuum in H and K, including contributions from circumstellar
flux and possible asymmetries.

TX Psc is a carbon star, i.e. V magnitude is variable with 
a maximum of 5. K magnitude is not expected to vary very much
and is around K=-0.7.

Visibilities in K are expected in the range 0.4-0.1, depending
on the UT baseline.

Any triplet of UT telescopes will do.

We prefer observations without IRIS, in order to record also
the H-band. For this, we assume that operation without IRIS
will satisfy the specifications of the CfP, i.e. at least 3%
visibility accuracy. Should experience at Paranal in P77
show that this is not the case, we would like to be consulted
again.

Special Calibration Information

Tet Psc is from the Calvin list, it is 5 deg from TX PSc,
with a K magnitude = 1.86.

Depending on the UT baseline, visibilities are expected 
in the range 0.66-0.95 in K
