0002740101 CFHT-Pl-12 appears to be the name of a CFHT plate, and the proposal 0002740101 abstract suggests that this is a field observation. 0002970401 The coordinates of the proposal position and image do not agree. The 0002970401 Observation Log Browser web-page at ESAC refers to an earth limb 0002970401 test. The field of the observation is therefore as a whole 0002970401 serendipitous. 0008820401 The observation of HD168112 was replaced by a ToO observation of 0008820401 GRB 020321 which, however, was not registered in the ODF. 0045340401 This is a double star but the X-ray detection is not at the Simbad 0045340401 position, and the field classification is ambiguous. 0045340901 This is a double star but the X-ray detection is not at the Simbad 0045340901 position, and the field classification is ambiguous. 0045341001 This is a double star but the X-ray detection is not at the Simbad 0045341001 position, and the field classification is ambiguous. 0045341101 This is a double star but the X-ray detection is not at the Simbad 0045341101 position, and the field classification is ambiguous. 0075940101 Simbad recognises the field name 30 Ari but returns two objects 0075940101 (30 Ari A and 30 Ari B). Due to the ambiguity no Simbad name and 0075940101 coordinates are given. 0093550401 This observation was intended to have Z And as a target but due to 0093550401 an operational issue a different position was observed. The field of 0093550401 the observation is therefore as a whole serendipitous. 0094360201 There seems to be an error in the proposal coordinates in the 0094360201 proposal; the field of the observation is therefore as a whole 0094360201 serendipitous. 0094380101 The observation of 1ES1255+244 was replaced by a ToO observation of 0094380101 GRB 011211 which, however, was not registered in the ODF. 0094530401 The observation has a large offset observation from 3C192. 0106860101 There is a source at the proposal position, however, it is possibly 0106860101 only a spurious extended detection, and therefore no source ID is 0106860101 given. 0108060401 The field name is AXAF Ultra Deep Field; this appears to be the same 0108060401 as the Hubble Ultra Deep Field with very similar coordinates 0108060401 (53.1625, -27.7914). 0108060501 The field name is AXAF Ultra Deep Field; this appears to be the same 0108060501 as the Hubble Ultra Deep Field with very similar coordinates 0108060501 (53.1625, -27.7914). 0108060601 The field name is AXAF Ultra Deep Field; this appears to be the same 0108060601 as the Hubble Ultra Deep Field with very similar coordinates 0108060601 (53.1625, -27.7914). 0108060701 The field name is AXAF Ultra Deep Field; this appears to be the same 0108060701 as the Hubble Ultra Deep Field with very similar coordinates 0108060701 (53.1625, -27.7914). 0108061801 The field name is AXAF Ultra Deep Field; this appears to be the same 0108061801 as the Hubble Ultra Deep Field with very similar coordinates 0108061801 (53.1625, -27.7914). 0108061901 The field name is AXAF Ultra Deep Field; this appears to be the same 0108061901 as the Hubble Ultra Deep Field with very similar coordinates 0108061901 (53.1625, -27.7914). 0108062101 The field name is AXAF Ultra Deep Field; this appears to be the same 0108062101 as the Hubble Ultra Deep Field with very similar coordinates 0108062101 (53.1625, -27.7914). 0108062301 The field name is AXAF Ultra Deep Field; this appears to be the same 0108062301 as the Hubble Ultra Deep Field with very similar coordinates 0108062301 (53.1625, -27.7914). 0109060201 Ambiguous because target name is not precise enough. 0109860101 The target name is A 189 but the proposal abstract indicates that 0109860101 NGC 533 group is the object. It is not obvious whether both are 0109860101 target. 0109860201 The target name is A 189 but the proposal abstract indicates that 0109860201 NGC 533 group is the object. It is not obvious whether both are 0109860201 target. 0109860401 The target name is A 189 but the proposal abstract indicates that 0109860401 NGC 533 group is the object. It is not obvious whether both are 0109860401 target. 0111520301 This is a ToO observation of GRB 010220, the field name as given in 0111520301 the proposal is wrong. 0112200601 Unclear whether the extended emission around the pulsar is connected 0112200601 to it, the field classification is therefore unknown. 0112200701 Unclear whether the extended emission around the pulsar is connected 0112200701 to it, the field classification is therefore unknown. 0112201101 pulsar is located in SNR W44 (cf. proposal-ID 008327), and extended 0112201101 emission is detected; the field classification is taken to be the 0112201101 same as for proposal-ID 008327. 0112260101 The target is a merging galaxy cluster, A399/A401. There are four 0112260101 observations in different offset positions. The Simbad column lists 0112260101 for each observation the cluster that is nearer to the centre of the 0112260101 FOV, where possible. 0112260201 The target is a merging galaxy cluster, A399/A401. There are four 0112260201 observations in different offset positions. The Simbad column lists 0112260201 for each observation the cluster that is nearer to the centre of the 0112260201 FOV, where possible. 0112260301 The target is a merging galaxy cluster, A399/A401. There are four 0112260301 observations in different offset positions. The Simbad column lists 0112260301 for each observation the cluster that is nearer to the centre of the 0112260301 FOV, where possible. 0112260401 The target is a merging galaxy cluster, A399/A401. There are four 0112260401 observations in different offset positions. The Simbad column lists 0112260401 for each observation the cluster that is nearer to the centre of the 0112260401 FOV, where possible. 0113050101 The proposal abstract mentions clumpy sources in the neighbourhood of 0113050101 pulsars, and the field classification is somewhat ambiguous (with 0113050101 respect to actual detections). 0113050201 The proposal abstract mentions clumpy sources in the neighbourhood of 0113050201 pulsars, and the field classification is somewhat ambiguous (with 0113050201 respect to actual detections). 0113050501 The proposal abstract mentions clumpy sources in the neighbourhood of 0113050501 pulsars, and the field classification is somewhat ambiguous (with 0113050501 respect to actual detections). 0113051301 The proposal abstract mentions clumpy sources in the neighbourhood of 0113051301 pulsars, and the field classification is somewhat ambiguous (with 0113051301 respect to actual detections). 0113051501 The proposal abstract mentions clumpy sources in the neighbourhood of 0113051501 pulsars, and the field classification is somewhat ambiguous (with 0113051501 respect to actual detections). 0135960101 The proposal abstract describes the object as Xray reflection nebula. 0135960101 There is no Simbad type for that but it seems appropriate to use. 0141610601 The Simbad position appears to be wrong (the coordinates in the name 0141610601 were assumed to be B1950 and converted to J2000 coordinates). 0143630201 This is a double star but the X-ray detection is not at the Simbad 0143630201 position, and the field classification is ambiguous. 0143630501 This is a double star but the X-ray detection is not at the Simbad 0143630501 position, and the field classification is ambiguous. 0149630301 The proposal explains LMC1 to be a supergiant shell, while Simbad 0149630301 knows only a symbiotic star named LMC1. Instead Simbad knows the 0149630301 supergiant shell as LMCSGS 1. 0154750401 Both the proposal position and the Simbad position are offset from 0154750401 the identified source. The correct identification of this source 0154750401 comes from other observations of the same object 0154750401 (proposal-ID 020100). 0154750301 Though the proposal position and Simbad position are not centred on 0154750301 the source identification given, the identification seems 0154750301 unambiguous (note that the Simbad position is not very precise which 0154750301 would explain the offset). 0201270101 The Simbad position appears to be wrong (the coordinates in the name 0201270101 were assumed to be B1950 and converted to J2000 coordinates). 0202940201 The declination is wrong, the field of the observation is therefore 0202940201 as a whole serendipitous. 0203540901 From the field name and proposal abstract it is not clear whether 0203540901 this is a field or point-source observation. 0204010101 The target is three point sources. 0204220101 The field name is a composite of several target names. 0204220201 The field name is a composite of several target names. 0204220301 The field name is a composite of several target names. 0206190101 According to the proposal abstract the target type is an X-ray 0206190101 compact source. 0206190201 According to the proposal abstract the target type is an X-ray 0206190201 compact source. 0210470601 This is an observation of a super-bubble; the field classification 0210470601 is ambiguous (x or l). 0210470701 This is an observation of a super-bubble; the field classification 0210470701 is ambiguous (x or l). 0210470801 This is an observation of a super-bubble; the field classification 0210470801 is ambiguous (x or l). 0210470901 This is an observation of a super-bubble; the field classification 0210470901 is ambiguous (x or l). 0303670101 The proposal abstract indicates that this is an observation of two 0303670101 galaxy groups, the Simbad name is given for the first name only. 0304050101 It is not clear if this is a point source or a small extended source.
