Position information for each 'non-fixed' pointing (slewing) observation. Note that the Aperture Shape can either be a 'R'ectangle or a 'C'ircle. Multiple pointing entries can exist for observations. These entries are distinguished by the position identifier (pid) column.

Validity of the pointing information in this table (UTC1 and UTC2) is derived by taking the time from the IIPH for a single pointing entry (the IIPH contains pointing entries with an interval of 0.5 seconds) and substracting 0.25 seconds to get UTC1 and adding 0.25 seconds to get UTC2.

column aid

Aperture id. Three characters: (i) instrument, (ii) aperture and (iii) aperture modifier.
See table aperture id (aid) for more information about possible values etc.

column dec

Center point declination. Units: degrees.

column mjd1

Expected start of pointing in Modified Julian Day.

column mjd2

Expected end of pointing in Modified Julian Day.

column obsno

Observation number constructed as follows:
revolution number * 1000000 + target number * 1000 + observation sequence number * 10 + type
See SCREW 385 for further details.

column pid

Pointing identifier. To distinguish multiple slewing (pointing) entries for the same observation (counting from zero).

column ra

Center point right ascension. Units: hours.

column roll

Center point roll angle. Units: degrees.

column rpid

Raster point identifier ; first two digits corresponding to raster-points along the horizontal axis, second two digits corresponding to raster-points along the vertical axis (will be set to '0101' for standard, non-raster pointings).

column shape

Shape of the aperture used:
C Circular
R Rectangular.

column utc1

Expected start of pointing in UTC since 1989.

column utc2

Expected end of pointing in UTC since 1989.

column utk1

Expected start of pointing in UTK. Calculated from utc1.

column utk2

Expected end of pointing in UTK. Calculated from utc2.
