Keyword Position Type Description
------- -------- ---- -----------
EVEF - CHAR The name of the input event file (default
extension of .EVE).
SHOW - LOGICAL Requests that a sub-set of the
information from the header records of
the event file is displayed.
OUTPUT - CHAR The name of the output dataset.
DTYPE - CHAR The type of dataset to be produced by the
sort. Valid types are
(I)mage ASTERIX image dataset
(R)aw detector coord image
(L)in linearised detector coord image
(T)ime time series dataset
(E)vent event dataset.
RA - REAL The Right Ascension of the sort field
centre (deg). By default this is set to
the axis RA value given in the header.
DEC - REAL The Declination of the sort field centre
(deg).
DAZ - REAL The half extent of the field to be sorted
(deg), the default value is 3 degrees.
INR - REAL In time series mode INR specifies the
inner radius of an annulus from which to
select events. The radius should be
specified in arcminutes and may be set to
zero in order to select from a circular
region.
OUTR - REAL In time series mode OUTR specifies the
outer radius of an annulus from which to
select events.
NXPIX - INT The number of pixels along a side of the
image. For the default field half extent
of 3 degrees NXPIX = 256 would give a
pixel width of approx 1.4 arcminutes.
SLOTS - CHAR A text string which specifies which slots
to include in the sort. (These are the
slots which are displayed when SHOW = Y
is selected). Specify the slots in the
format i-j,k,l-m. The slots selected
should all have the same filter at the
focus. If a slot value of '0' is selected
the user is prompted for the filter type
instead.
START_T - REAL*8 The start time of a selection window
which will be combined with the slot and
discrimination windows. The unit may be
either seconds from the BASE_MJD given in
the EVE file header or an absolute MJD
(in the latter case the MJD value should
be preceded by an 'M').
END_T - REAL*8 The end time of a selection window (see
above)
USEF - LOGICAL Requests that events will be selected
from time windows specified in a simple
text file.
SFILE - CHAR The name of a text file from which the
time windows will be read. Each record in
the file should contain a pair of start
and stop MJDs separated by a space and
with each MJD preceded by the letter 'M'.
NBINS - INT The number of time bins. If a value '0'
is given the program prompts for the bin
duration instead.
TBIN - REAL If NBIN is specified as 0 then TBIN
specifies the bin duration (secs)
FILTER - CHAR The WFC filter to use.
REJECT - CHAR Requests rejection of events by one of
the 'LEVS', or 'VIEW' options. If VIEW
event rate thresholding is selected all
events from periods when the
velocity-view (or ram) angle .OR. the
solar zenith angle was below certain
limits will be rejected. The optimum
values for these angles are set by the
program. Alternatively the parameter may
be set to 'NONE'.
LEVS - REAL If LEVS event rate thresholding is
selected all events from periods when the
LEVS rate exceeds this threshold will be
rejected (suggested start value is 50 c/s)
ROOT - CHAR The File root which defines the location
of the .HKR file used for LEVS
discrimination.
