esky2det (esky2det-1.20) [22.0.0-9173c7d25-20250127]

Parameters

This section documents the parameters recognized by this task (if any).

Parameter	Mand	Type	Default	Constraints
datastyle	no	string	set	user|set
By use of this parameter, the user can specify the style of input and output desired. If datastyle=`user', the task looks for position information for a single source in the parameters ra and dec. If datastyle=`set', the task looks for the source positions stored in columns RA and DEC of a FITS table specified by the parameter intab.
intab	no	table	inset.ds:INPUT
Name of the FITS table that contains the sky positions. Active only if datastyle=`set'.
witherrorcol	no	boolean	no
Active only if datastyle=`set'. If witherrorcol=`yes', esky2det looks for position uncertainties in decimal degrees in columns RA_ERR and DEC_ERR of intab. If neither of these columns is found, esky2det looks for a common value in arcseconds stored in a column named RADEC_ERR. This last is to cater for the format of source lists output by emldetect.
withouttab	no	boolean	no
Active only if datastyle=`set'. If withouttab=`yes', the task looks for outtab and writes the output to this file. Otherwise the output is written to columns in the intab.
outtab	no	table	outset.ds:OUTPUT
Name of the FITS table that is to contain the camera-centric positions. Active only if datastyle=`set' and withouttab=`yes'.
ra	yes	angle	0.0	$0\le$ra$\le360$
The right ascension (in any of the allowed angle-parameter formats) of the source. Active only if datastyle=`user'.
dec	yes	angle	0.0	$-90\le$dec$\le90$
The declination (in any of the allowed angle-parameter formats) of the source. Active only if datastyle=`user'.
witherrorradius	no	boolean	no
Active only if datastyle=`user'. If witherrorradius=`yes', esky2det reads a single angular uncertainty from parameter errorradius.
errorradius	yes	angle	0.0	$0\le$errorradius
The radius of the uncertainty circle around the source position. Active only if datastyle=`user' and witherrorradius=yes.
withheader	no	boolean	yes
Active only if datastyle=`user'. If withheader=`yes', the task prints some lines of header information before printing the source position line; if `no', this is omitted. The `no' setting is convenient for those wishing to run esky2det from a script.
outunit	no	string	raw	det|raw
If outunit=`det', the positions are calculated in the DETX/Y system. Otherwise, the RAWX/Y and CCDNR of the position are calculated.
mosccdnode	no	string	primary	primary|redundant
This allows the user to specify the readout node for positions on the MOS instruments. It is enabled only if outunit=`raw', and ignored for PN.
calinfostyle	no	string	set	set|user
If `set' the task obtains information about the instrument and spacecraft pointing from calinfoset; if `user', this information is obtained from parameters instrument, datetime, scattra, scattdec and scattapos.
calinfoset	yes	dataset	calinfo.ds
The name of the dataset in which information about the instrument and spacecraft pointing etc is stored in keywords.
instrument	yes	string	EMOS1	EMOS1|EMOS2|EPN
Active only if calinfostyle=`user'. The name of the relevant XMM instrument.
datetime	yes	string	0000-00-00T00:00:00
If calinfostyle=`user', the date and time are expected via this string parameter.
scattra	yes	angle	0.0	$0\le$attra$\le360$
The right ascenscion (in any of the allowed angle-parameter formats) of the spacecraft pointing. Active only if calinfostyle=`user'.
scattdec	yes	angle	0.0	$-90\le$attdec$\le90$
The declination (in any of the allowed angle-parameter formats) of the spacecraft pointing. Active only if calinfostyle=`user'.
scattapos	yes	angle	0.0	$0\le$attapos$\le360$
The position angle (in any of the allowed angle-parameter formats) of the spacecraft pointing. Active only if calinfostyle=`user'.
checkfov	no	boolean	yes
If set true then the task does not return detector coordinates for positions which don't lie on a CCD or within the field-of-view. Set to false to get a DET value for these cases.
