Increasing this number allows more
observations per block [2].
This is of particular advantage when
MBIAS, PBIAS or EBIAS options are invoked
along with local pass editing (see EDIT
card column 7).
This options consumes considerably more
memory and is therefore disadvantageous
to large E-Matrix generation runs.

A good estimate for the total disk space
required for all of these scratch files
may be obtained by multiplying the number
of weighted observations plus twice the
number of E-biases by the number of
adjusted parameters and dividing by 512.

NOTES:
[1] The Tracking Data Formatter program outputs a maximum of 9999 obs.
per block. GEODYN-IIS may reduce the number of observations in a
block but not increase it. By reducing the number of observations
in a block, memory requirements are decreased. This may be required
when a large number of parameters are estimated.
[2] Values in columns 11-14 and 15-17 are automatically provided by NORMPT
option.
[3] Partitioning is automatically requested for E-matrix runs regardless
of the value indicated in column 7.
IF CARD OMITTED: Default optimizations will be used.
