Abstract:
We describe a large-scale far-infrared line and continuum survey of
protoplanetary disk through to young debris disk systems carried out
using the ACS instrument on the Herschel Space Observatory. This Open
Time Key program, known as GASPS (Gas Survey of Protoplanetary
Systems), targeted ∼250 young stars in narrow wavelength regions
covering the [OI] fine structure line at 63um the brightest
far-infrared line in such objects. A subset of the brightest targets
were also surveyed in [OI]145um, [CII] at 157um, as well as several
transitions of HO and high-excitation CO lines at selected wavelengths
between 78 and 180um. Additionally, GASPS included continuum
photometry at 70, 100 and 160um, around the peak of the dust emission.
Description:
The project was awarded 400 hours of time to survey up to 250 young
systems (in several cases, multiple systems were covered in the same
observation), and observations were taken at various times between Dec
2010 and July 2012.

Note (1): The table is ordered by association or group and then RA.
Coordinates are the pointing position of the observations, and may be
centred between multiple systems. Key to the naming convention is:
T = Taurus
S = Upper Sco
E = η Cha
W = TW Hya,
B = β Pic Moving group
H = Tuc Hor,
A = Herbig AeBe stars and A stars with debris disks (noted in
column "Notes" as D)
C = ChaII.
Note (2): For multiple systems, we give either only the primary, or the
brightest components when these are separable in PACS.
Note (3): Hα equivalent width is given as positive for an emission
component. Blank indicates no measurement. An average from published values
for the most luminous component in indicated, or both components when they
are separable with PACS. Note that the HW is highly variable in many objects.
Note (4): Class from the literature, if available:
I-II = IR excess (II defined as -0.3>αIR>-1.6)
III = αIR←1.6, which includes stars without a measured IR excess
TO = Transition Object, defined as a Class III object with an additional
excess at wavelengths longer than 10um),
D = classed as a debris disk.
Note that for the Herbig AeBe stars, the SED classification is instead
based on the Meeus SED groups I and II - see Sect. 5.0.9 for details.
Blank means no excess is known in either the IR or longer wavelengths.
Note (5): Disk dust mass, derived in most cases from published mm/sub-mm
observations (see section 5.0 for references). Upper limits are 3σ.
Lower limits are normally based on fits to FIR photometry, where no
sub-mm datapoint is available. Note that disk mass for protoplanetary
disks is normally assumed to be 100Mdust.
Note (6): Summary of line detections from PACS of [OI]63um, [CII]157um,
CO J-18-17 and H2O (any transition detected, most commonly the line at
63.3um - see text) as follows:
1 = indicates detection
0 = means not detected
: = means not observed.
Note (7): Abbreviations used in notes:
Jet = indicates published evidence of an optical jet
Ext.OI = indicates the [OI]63um emission appears extended
high(dM/dt) = indicates high published mass loss rate
(see Sect.5.2.1 and 5.2.2 for details)
Mult. = indicates a multiple hierarchical system
i = Membership is now in doubt - see Luhman et al. (2009ApJ...703..399L 2009ApJ...703..399L)
