Parameter | Mand | Type | Default | Constraints |
datastyle | no | string | user | 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 intable.
| ||||
witherrors | no | boolean | no | yes/no |
If this parameter is set, the task looks for (and transforms) uncertainties in the sky position read, depending on the setting of datastyle, either from parameters raerror and decerror, or from columns RA_ERR and DEC_ERR (or, if these are not found, RADEC_ERR) of intable.
| ||||
intable | no | table | srclist.ds:SRCLIST | |
Name of the FITS table that contains the sky positions. Active only if datastyle=`set'.
| ||||
withouttable | no | boolean | no | yes/no |
If datastyle=`set' and withouttable=`yes', the task looks for outtable and writes the output to this file. datastyle=`set' and withouttable=`no' causes the output to be written to columns in the intable.
| ||||
outtable | no | table | srclist.ds:SRCLIST | |
Name of the FITS table that is to contain the camera-centric positions. Active only if datastyle=`set' and withouttable=`yes'.
| ||||
ra | no | angle | 0.0 | ra |
The right ascension (in any of the allowed angle-parameter formats) of the source. Active only if datastyle=`user'.
| ||||
dec | no | angle | 0.0 | dec |
The declination (in any of the allowed angle-parameter formats) of the source. Active only if datastyle=`user'.
| ||||
errorradius | no | angle | 0.0 | errorradius |
The radius of the uncertainty circle around the source position. Active only if datastyle=`user' and witherrors=yes.
| ||||
outunit | no | string | det | 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.
| ||||
instrument | no | string | null_default | null_default/m1/m2/pn |
The relevant XMM instrument. If this is left at `null_default', the task attempts to look for the instrument in the INSTRUME keyword in the header of intable, where this is supplied. instrument=`null_default' and datastyle=`user' will result in an error.
| ||||
node | 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.
| ||||
attstyle | no | string | intable | user/inset/mean/median |
Style for entry of the attitude or pointing information. If attstyle=`user', the information should be supplied by the user directly via the attra, attdec and attapos parameters. If attstyle is `mean' or `median', the user should supply an attitude history file (made by atthkgen) via the parameter atthkset: esky2det
then reads the pointing from the appropriate keywords of this file. The final alternative, `inset', directs esky2det
to look for RA_PNT, DEC_PNT and PA_PNT keywords in the primary header of the dataset named by parameter intable, if this has been supplied. Clearly the combination of attstyle=`inset' and datastyle=`user' will result in an error.
| ||||
attra | no | angle | 0.0 | attra |
The right ascenscion (in any of the allowed angle-parameter formats) of the spacecraft pointing. Active only if attstyle=`user'.
| ||||
attdec | no | angle | 0.0 | attdec |
The declination (in any of the allowed angle-parameter formats) of the spacecraft pointing. Active only if attstyle=`user'.
| ||||
attapos | no | angle | 0.0 | attapos |
The position angle (in any of the allowed angle-parameter formats) of the spacecraft pointing. Active only if attstyle=`user'.
| ||||
atthkset | no | dataset | atthk.dat | |
The name of the attitude history file created by atthkgen. Necessary only if attstyle=`mean' or `median'.
| ||||
timestyle | no | string | obsstart | obsstart/user |
This controls the way in which date and time information (necessary to allow the task to interpolate the boresight correction) is supplied.
| ||||
datetime | no | string | 0000-00-00T00:00:00 | |
If timestyle=`user', the date and time are expected via this string parameter.
