Hi Raphael, the reason for this is that we haven't updated the crossmatches table for some time. We are working in a new version which is up to date, which will be released soon. For the moment you can remove the requirement of having a crossmatch. See attached
Thank you. I am also getting an issue with pip install alerce_client:
"Collecting alerce_client Could not find a version that satisfies the requirement alerce_client (from versions: ) No matching distribution found for alerce_client"
Getting the code from https://github.com/alercebroker/alerce_client and installing does seem to work. Perhaps pip hasn't been updated yet...
Best,
Raphael.
Hi Raphael, thanks for the feedback. Can you send us more details about your operating system, python version, etc...? You can install locally from this repository: https://github.com/alercebroker/alerce_client You will need pandas >= 0.24
@cvalenzu any ideas what could be the problem?
I'm using a mac. Directly installing from the GitHub code works. I use conda and pip, pandas 0.24, python 3.6.
Hmm I am also getting an issue with the queries giving me objects with dates below the minimum I set. The following returns objects with firstmjd below 58700:
` total = 100 records_per_page = 100 page = 1 sortBy = "pclassrf" classrf = "SNe" pclassrf = 0.8 min_nobs = 10 max_nobs = 50 min_firstmjd = Time("2019-09-19T00:00:00", format="isot", scale="utc").mjd - 14
params = {
"records_per_pages": records_per_page,
"page": page,
"sortBy": sortBy,
"query_parameters": {
"filters": {
"nobs": {
"min": min_nobs,
"max": max_nobs
},
"firstmjd": {
"min": min_firstmjd,
},
"classrf": classrf,
"pclassrf": pclassrf
}
}
} SNe = alerce.query(params) print(SNe.shape) SNe.head() `
Thanks for the input, we can reproduce the error you mention. I think there is a bug in the API, let us fix it and we will let you know once it is fixed.

Hi,
The package is called just alerce
, to install it run pip install alerce
and to import the client run from alerce.api import AlerceAPI
Hi Raphael
We found the problem, the params were incorrectly formatted. "firstmjd" must be inside the "dates" key. Try the following formatting:
total = 100 records_per_page = 100 page = 1 sortBy = "pclassrf" classrf = "SNe" pclassrf = 0.8 min_nobs = 10 max_nobs = 50 min_firstmjd = Time("2019-09-19T00:00:00", format="isot", scale="utc").mjd - 14 print(min_firstmjd) params = {
"records_per_pages": records_per_page, "page": page, "sortBy": sortBy, "query_parameters": { "dates": { "firstmjd": { "min": min_firstmjd, } }, "filters": { "nobs": { "min": min_nobs, "max": max_nobs }, "classrf": classrf, "pclassrf": pclassrf } } } SNe = alerce.query(params) SNe.head()
which returns one object
If I run the SN notebook:
https://github.com/alercebroker/usecases/blob/master/notebooks/ALeRCE_ZTF_SupernovaUseCase.ipynb
But change the date in the query in cell 12 to look for sn at least 70 days after first light to the last 100 days it returns no objects.
What am I doing wrong?
Many thanks,
Raphael. (postdoc at IAC)
