v0.10.12

Merge pull request #818 from linea-it/develop

Fixed upload small lists with integer values and problem with objects that have the id string.

v0.10

Sky Viewer

Aladin snapshot only in Firefox.
Change cursor type according to operation mode.

Target Viewer

1. Pan viewer included.
2. Change cursor type according to operation mode.
3. Fix: more flexible format (spaces and integers); allows to register tables with ID as string.
4. Fix: View page objects counter.
5. Enable Explorer for coadd objects.

Notes:

1. The limit in the number of cutouts is still under discussion with NCSA. At the moment it is hardwired to be 100 to facilitate debugging. In the future one should make this operation more flexible by perhaps either choosing the number or allow the selection of individual entries.

2. At the moment cutouts for fields located between 180 and 360 are not working because of convention problems between the portal and Descut.

Depth, Coverage and Systematic Maps

These maps represent a Healpix version of different astronomical properties distribution across the sky. Given that each point in the footprint is the combination of information of stacks of images, a statistic has to be used to summarize this information for that particular point. The complex geometry of the survey is kept track through the Mangle software (run by DESDM as an afterburner of the coadd pipeline) and then “Healpixelized” to provide the maps made available here.

The properties of the maps are: nside=4096, order=nested.

We divided those into 3 different classes: depth maps, coverage maps and systematic maps.

– Depth maps represent the magnitude limit for a given magnitude system as a function of position in the sky, and given a snr ratio. For now, only magnitude limit in 2” (mag_aper4) at 10sigma is present. This is the default variable coming from DESDM, as read from the Mangle products.
– Coverage maps: These maps represent the survey footprint for each band separately, and also for the combination of various bands together, in particular, we present the coverage map for g,r,i,z,Y separately, and another coverage map for the combination of griz and another for grizY.
– Systematic maps: These maps keep track of the spatial variation of several statistics concerning the imaging conditions of the survey across the sky.

• Detection fraction: what fraction of the Healpix pixel has been observed (according to Mangle geometry) in each band or simultaneously in griz or grizY bands.
• Exposure time: the time in seconds for exposures in a given filter (EXPTIME) or the effective time (TEFF_EXPTIME), weighted with atmospheric transmission, seeing and sky brightness (see here).
• Airmass: secant of the zenith angle for the observations included in the pixel.
• Seeing: measures the sky quality as a blurring of point-like sources, it is described here as the full width half maximum (in arcseconds) of the PSF taken from FWHM_MEAN of the PSF_QA table (calculated using PSFEx). The FLUXRAD quantities are obtained using the flux radius in PSFEx (TBC)
• Sky variance: this is the fluctuation of the sky brightness, weighted using the weight map from DESDM
• Zero point residues from FGCM: residual “gray” corrections from FGCM calibration (section 3.3 of the FGCM paper)

The statistics used are:

• WAVG: weighted averaged mean of the quantity, considering the noise weight map produced by DESDM
• MIN: minimum of the quantity among all the contributing images.
• MAX: maximum of the quantity among all the contributing images.
• TOTAL, SUM: sum of the quantity for the contributing images.
