Basic Information on clstats
Task: clstats
Purpose: Calculates dispersions, masses, etc for each clump from clfind file
Key: in
file name of data cube
(no default)
Key: dist
the distance to the object in pc
(no default)
Key: disterr
multiplicative error in the distance
eg disterr=2 means dist is uncertain by a factor of 2
(default=1)
Key: x
the X-factor to convert between column density of the
species observed to the column density of molecular hydrogen
--- see above. (Note that this includes any corrections for
abundance, excitation temperature, CMBR, antenna efficiency,etc.)
(In units of 10^20, default=2.4)
Key: xerr
multiplicative error in X -- from uncertainties in
abundances, excitation temperature, efficiency, etc.
(default=1)
Key: meanmol
the mean molecular weight of the gas
(default=1.38, corresponding to n(He)/n(H)=0.1)
Key: jyperk
the number of Jansky's per Kelvin for these observations
(default=1)
Key: xy
"rel" or "abs" for the clump positions - v is always absolute
(default=relative)
Key: rms
optional input to specify the rms error in temperature
for each pixel in the map (used to calcuate errors in
the masses). Otherwise 0.5*DeltaT, where DeltaT is the
clfind contour interval.
Key: nmin
each clump must contain at least nmin pixels to be
written out to output file
(default=4)
