scaleSynphot does not recognize ULTRASAT filters at last08e

[agioffe]

at last08e and RC configuration:

sudo last-tool -n enforce last-software --space rc --repo AstroPack matlab

S = AstroSpec.blackBody(2000:11000,3500); Sc = scaleSynphot(S,20,'SDSS','g');

Sc2 = scaleSynphot(S,20,'ULTRASAT','R1'); Index exceeds the number of array elements (0).

Error in AstroSpec/synphot (line 1745) [Mag, FiltFlag, FilterWave(Iname)] = astro.spec.synthetic_phot(Spec, FilterCell{Iname}, [], Args.MagSys,...

Error in AstroSpec/scaleSynphot (line 1798) MagSyn = synphot(Obj, FilterFamily, FilterName, 'MagSys',Args.MagSys, 'Device',Args.Device);

What could be the reason? Some of the filter data are missing? At the local machine (at WIS) on dev1 branch both variants work normally:

clear all S = AstroSpec.blackBody(2000:11000,3500); Sc = scaleSynphot(S,20,'SDSS','g'); Sc2 = scaleSynphot(S,20,'ULTRASAT','R1');

Hi,

I suspect that +cats is not installed and therefore, there are no filters available and you can use AstFilter. Please check if +cats is installed.

I've checked it first of all. There is a ~/matlab/data/+cats directory and the +filter directory in it, and the appropriate .mat and .m filter files inside like at the local machine. This is why I was puzzled and raised this issue..

[EranOfek]

on this machine, please try to read some filters: R=AstFilter.get('SDSS','g') is this working?

next try: R=AstFilter('ULTRASAT','R1') is this working?

If the second command doesn't work than the version on this computer is not up to date. This is not important, because LAST computers doesn't care about ULTRASAT filters.

[agioffe]

Yes, there is a problem with ULTRASAT filters here. How could I repair it?

R=AstFilter.get('SDSS','g')

R =

AstFilter with properties:

         family: 'SDSS'
           band: 'g'
              T: [68x2 double]

you need to copy the +cats directory from e.g., euler

[agioffe]

Eventually, I managed to fix it by just copying into the +cats/+spec/ files named a.mat and a.m from my local machine. Thank you!
