This is the complete set of model HVCs described by 
Heitsch & Putman 2009, ApJ, 698, 1485 (HP09). The table contains
all HI clouds identified by a temperature threshold (T<10000K).
Objects with less than 27 cells have not been catalogued.
For more details on the simulations, see HP09.

Please understand that these are model clouds, and as such
are affected by numerical resolution. Personally, I would
be hesitant to trust any structures with less than, say, 
300 cells. You are welcome to use this dataset under the 
condition that you cite HP09, mentioning explicitly this
publicly available table. Although the table has been 
assembled with great care, no guarantee to its accuracy 
can be given. If you do find any inconsistencies or errors,
please let me know.

Here's a short description of the table columns:

1st column: model name as in HP09
2nd column: internal model number, corresponding to name 
            (for easier selection)
3rd column: dump number: this is essentially a time step number
4th column: cloud number: for each model and dump, running number
            of cloud as identified by clump finder (see HP09).
            Example: cloud=0 is usually the most massive fragment,
            so for a given model, a sequence in dumps for cloud=0
            returns the time evolution of the most massive fragment.
5th column: number of cells (resolution elements) in cloud. Use
            as estimate how much to trust a given cloud.
            Just masses should be fine down to ~60 cells. Internal
            velocity dispersions I would not trust below ~300 cells.
6th column: cloud mass in solar masses
7th column: 3D velocity dispersion in km/s. To get 1D FWHM, divide 
            by sqrt(3) and multiply by 2.35
8th column: center-of-mass velocity (in km/s) of cloud (with 
            respect to background medium).
9th column: size of cloud in pc, computed via cubic root of cell
            number.
